Sigma ROX 11.0 Review

In February 2017, Sigma released an all new ROX 11.0 unit, aimed at replacing their aging ROX 10.0 unit. More than just a cosmetic update, the ROX 11.0 is feature packed, and a notable improvement over the ROX 10.0. I’ve been reviewing the new unit over the past few months, while it’s not as fancy as a Garmin it’s certainly a no nonsense unit.

Old vs new… looking silly for the sake of comparison

Before delving into the new software features, the hardware of the ROX 11.0 has been improved over it’s predecessor. The device now supports both bluetooth as well as ANT+, and has a longer battery life and more memory. There’s enough memory to store more than 50 hours of riding even when recording every second, and the battery life has been bulked up to a claimed 19 hours.

The improved battery and storage mean you can now go longer without charging and clearing memory. In addition, the bluetooth connectivity allowed the ROX11.0 to sync data wirelessly through compatible phones via Sigma Link, as well as display notifications. In my experience while the live notifications was useful, the wireless uploads were slow, each ride would take a couple of minutes. I also couldn’t get my Sigma Link app to sync with TrainingPeaks so in the end I preferred using my laptop.

However, having despite my issues with TrainingPeaks, I found these features useful when away from home, especially if there was no stable Wifi connection. I could upload my rides to Strava (via my phone) and view (roughly) how my training/racing went. I’d still need to download my rides after returning home to log them on TrainingPeaks, but I’d imagine if the whole package worked as advertised (and perhaps I just had some teething issues) then this would have been extremely useful for trips away.

In addition, once you’ve finished a ride, the ROX can also display some useful training metrics such as your normalized power, your TSS and your averages. Again you could view this on TrainingPeaks/Golden Cheetah, but when you don’t have access to a laptop it’s particularly handy for gauging how your session went. I enjoyed being able to view these stats between stages on multistage days. One criticism was that I couldn’t work out how to have heart rate TSS displayed, (the TSS option I found was for power) and I feel that this feature would be useful for those without a powermeter.

Post ride summary, ROX pretty much displays everything you would want to know, averages, totals etc.

You can now also customise the ROX displays, but only via Sigma Data Center (on a PC or Mac). I found this extremely useful, and doing it on a PC means you don’t have to scroll through endless data fields to find the metric you want. You can not only customise the display fields, but you can also customise the size, shape, arrangement and number of fields as well. Sigma provide a lot of templates for data display, and within reason there were no restrictions on how you can display your data. If like me, you like to have a certain metric displayed bigger, and in the top left corner you will appreciate this detail. Stating the obvious, I found this extremely useful for displaying exactly what data I wanted to see. This has been a gripe of mine with the ROX 10, since the customization was much more restricted.

Customising the pages on ROX 11, lots of options and very user friendly

I’m not well versed in how these devices locate a GPS signal, but I’ve found the ROX 11 to be much faster at locating a signal than the ROX 10. This made the breadcrumb navigation much easier, I wouldn’t have to wait 5 minutes to find a GPS signal. It’s worth mentioning that navigation with maps isn’t supported. Judging by the user interface and relatively low screen resolution, it appears difficult to implement. I would suggest that this would be the most noticeable feature lacking on the ROX, and I suspect Sigma neglected this feature to hit their target price.

Sigma haven’t compromised on the screen quality though. The numbers are extremely easy to read and I had no issues with glare no matter what time of day. The front plastic/glass is also reasonably hard so you don’t need to worry about it scratching in your bag. I haven’t noticed anything that would suggest a cheap build quality.

One annoyance I’ve had with this device is that it seems to stop displaying external sensor data once you’ve saved an activity. In other words, if you stop and save a ride and then try to start a new ride you’ll be left with no data from ANT+/bluetooth sensors for that ride. Once you restart the device (turn it off and on)  all the sensors work as normal though. Not a deal breaker for me, but just keep this in mind if you also like to keep your warmup file separate from your race file.

Let there be power, heart rate and cadence… Had to turn my GPS off and on mid TT to register ANT+/bluetooth sensors

Sigma also offer the ROX 11.0 as a package with a speed/cadence and heart rate sensor, and I wouldn’t hesitate to recommend this option if you don’t already have these accessories. Both bundled accessories are dual bluetooth and ANT+, so definitely future proofed. The heart rate strap is very comfortable, and I prefered it over the Garmin strap. The speed cadence sensor is an ‘old style’ GSC-10 like unit (uses magnets) and I personally favour this over the latest accelerometer based sensors (call me old fashioned). Sigma have designed the sensor well, allowing the speed magnet sensor to be adjusted independently of the cadence sensor, so it should work with all frames. They also flash red/green to signify that the speed/cadence magnets are within range. Through my review period I’ve found that both accessories performed (marginally) better than the Garmin counterparts they replaced

Speed/cadence sensor – solid weight, 17g incl. battery

Heart rate sensor + strap. Strap=28g, sensor=13g incl. battery


Finally, Sigma moved away from their proprietary mounting system for the ROX 11, and they now use a ‘standard’ Garmin quarter turn mount. I didn’t have any issues with the ROX 10 mounting, but out front mounts for Garmin are far more common, so I welcome this move. I used a Garmin mount with no issues for the whole of the review period.

Everything considered, I’ve been impressed by the ROX 11.0, it’s got all the features I need to train effectively and the screen is easy to read mid-race. It lacks the features (and price tag) of a Garmin 520 or Wahoo Bolt, but actually I find it more appealing because of this. Provided Sigma rectify the issues I had with TrainingPeaks and sensors dropping out, I’d consider the ROX 11 as a perfect fit for me. However if you want better navigation and smartphone/trainer integration this computer may be a little lacking. That said, I’m not aware of any options at this price point that offer these features. RRP is $259.99 for the set (tested) or $179.99 for the unit.

I’ve been a little bad in that I haven’t tried using Strava live segments with this device. However it is supported, and I haven’t seen anything from the other features to suggest that it’s poorly implemented. I’d like to thank Starbike for providing the review sample.

DT Swiss RR411 Rim

Solid, wide and reasonably light would be my summary of the DT Swiss RR411 rims. Released in late 2016, I’ve had the pleasure of testing these rims long term. They’ve been through everything, from casual commutes to racing state championship events.

While not very aero, these wheels are a solid option for almost everything. I thought I’d TT on them.

Since this is weightweenies I’ll begin with the most important metric: aerodynamics weight. I tested the 21.5mm wide front and rear specific rims. From my sample of 1, the front (symmetric) rim weighs in at 436g and the rear (asymmetric) rim weighs in at 465g. At first glance this weight seems quite disappointing, especially considering DT recommend using washers between the rim and the nipples (supplied) . However, these rims are slightly lighter than HED Belgiums, H+Son Archetypes and Easton R90SL, even including the washers. It’s worth noting though that the rims are shallower (21mm) than the above options, and in some cases narrower too (18mm internal).

While the lower rim depth could deter some buyers, it may have contributed to their stability. In some windy races I noted my competitors having trouble with their deeper rims, while I was able to relax and stay focused on the racing.  These rims were dead straight in cross winds and I was able to ride confidently through technical sections in gusts of over 60kmph. The high quality braking surface meant braking could be left late and combined with the cross wind stability made these rims an excellent choice for those looking for extra confidence. As an aside, the rims were also really well balanced, perhaps another reason why the overriding sensation on was of speed and stability.

Climbing was also fun on these rims and at no point did they feel lifeless or hefty. Stiffness was good, and I was only able to obtain flex when I went looking for it, throwing my bike around in a huge gear. When my form was good, I couldn’t get any movement even doing big gear starts. These rims responded exceptionally to accelerations and steady state riding. This was true for spinning a smaller gear and mashing a big gear, so it’s certainly not a rim designed solely for wispy climbers with good technique.

Between climbs and descents there was still an overall feeling of smoothness and speed, though you can argue that those sensations were due to tyre and hub choices. I didn’t notice any ‘lack’ of aerodynamics that the low profile would suggest when riding. Based on my times there may be an edge to deeper race wheels. However I’ve been riding these wheels through winter, where lower temperatures, stronger winds and higher pressure may have had more of an effect. These wouldn’t be my first pick as race wheels but at the same time I don’t feel held back. I’d be perfectly happy to race these at weekend club races.

Of course, not all of this excellence can be attributed just to the rims, had I built this with flexy spokes and poor hubs I doubt they would have shone. For the review I was supplied with DT240s hubs and DT swiss competition spokes. If this was my own money I would have picked the DT350 hubs, but I’m never going to say no to 240 hubs. I picked a 28/32 spoke count for this build, which is the highest spoke count DT offer. With the low spoke count trend I presume DT decided higher drillings wouldn’t be worth their while (I’ve nearly got double the number of spokes of Shimano wheels!). The competition spokes suited these rims well, not aero but a reasonable weight with good stiffness. DT Swiss also kindly supplied some alloy pro-lock nipples and tubeless tape.

For those interested the total build came in at 1682g, you’d be able to save quite a few grams by going to a 20/28 or 20/24 build and aerolite/cx-ray spokes. A mid/high 1400g, low 1500g build is certainly possible without any exotic parts. This is what I would have done if I wanted race wheels which I’m not afraid to train on, rather than training wheels which I’m not afraid to race on.

The RRP for these rims starts at $98.60 (USD), which is quite expensive compared to Kinlin rims, but when you compare with similar quality rims like the HED Belgium it’s reasonable. Personally, I’ve always been in the Kinlin camp, but that’s not to say I don’t appreciate the finish quality and roundness of these rims. The cheaper rims aren’t bad, these are just better finished (and more expensive).

Shallow rims on a modern bike, yes or no?

In case it isn’t clear by now, I’m suitably impressed by these rims. It’s a high calibre rim, and can not only serve racers looking for a strong, wide yet light training rim, but it would also be suitable for those wanting a classy Saturday best rim. The key to both applications (and anything in-between) would be an appropriate spoke count, and DT offer a wide selection (20/24/28F and 24/28/32R).

Unfortunately I wasn’t able to test out the tubeless capabilities of these rims, but these rims have a very low profile hook so I imagine tubeless mounting shouldn’t bee too difficult. They’re also available in a disc specific version, which is slightly lighter at a claimed 410g.

We’d like to thank DT Swiss and Starbike for supplying the review sample.

Specialized S-Works Power Test

When Specialized first unveiled the Power saddle I immediately dismissed it as one that wouldn’t work for me. When riding I like to switch between sitting on the rearward half of the saddle, and riding on the rivet. However, when a friend offered to lend me his S-Works power to try I was curious. Now having ridden it for a few months I like it so much I’m not giving it back.

First things first, setting up the Power is quite different to other saddles. I’ve always positioned my (Selle Italia SLR) saddles so the nose is always a fixed distance behind the bottom bracket, but this won’t work when using the Power. Instead, I’ve found that a better guide is the position where the saddle transitions from ‘straight’ to curved. My experience suggests that placing the Power so the curved section aligned with an SLR resulted in an agreeable position. The picture below demonstrates how I set the Power in relation to an SLR (apologies for the dirty saddle – I swear I obtained it in that condition).

power crop

Specialized recommend increasing your setback by 3cm when using the Power. I found this recommendation vague, though useful. It is true that my setback increased by around 3cm (it’s a little under 3cm), so it’s a useful figure to start with, however I found more fine tuning was necessary. Perhaps changing from another Specialized branded saddle requires 3cm, but in relation to an SLR I discovered that aligning the ‘maximum curvature’ zone to be more practical.

It is true that I’m not able to slide forward on the Power, but after extensive riding I haven’t found this to be an issue. It’s not that I’ve got the saddle slammed forward, in fact my installation actually biases the rearward position. I’m not quite sure why I don’t miss the sitting on the nose, but one hypothesis is that I didn’t really ‘need’ to slide forward, rather it was just a bad habit. Now that I don’t have the option of sliding forward I can focus more on actually getting the power out, rather than moving into a position where I think I’m getting the power out.

In terms of what the Power feels like on the road, it is surprisingly similar to the Selle Italia SLR gel flow saddle (albeit with no nose to sit on). visually, the radius of curvature of both saddles is similar, though the Power is slightly wider (143mm vs 132mm) and shorter (~250mm vs ~270mm). The Power definitely feels supportive and encourages you to hold yourself steady in the saddle, minimising any rocking you may have. The Pro and S-Works model saddles are a little firmer than my SLR, but Specialized offer Expert and Comp level saddles which feature (slightly) softer padding. I personally preferred the firmer saddle (more on this later).

Despite being a new product the Power comes in 4 distinct models, with a Comp, Expert, Pro and S-Works model being available. ‘Distinct’ is a little misleading since the Comp/Expert and Pro/S-Works share the same shell/padding but differ in terms of rail material (so really 2 distinct models each with 2 rail options). I’ve been lucky enough to test both the S-Works and Pro model and I would suggest that both feel identical. If weight were of no concern I would save the money and buy the Pro model.

Speaking of weight, the Pro model weighs in at 211g according to my kitchen scales. I’m a little disappointed by the weight, my old SLR kit carbino saddles were around 135g and even the lower end SLR xp saddles were ~180g, both lighter than the Pro and S-Works model saddles. The inner weightweenie doesn’t like the saddle, but it’s proved itself over the last 6000km of training and racing. If pricing was more competitive I would have this saddle on all of my bikes.

power weight

Why don’t I think the pricing is competitive? The cheaper Comp and Expert models (despite sharing the same name) are actually very different saddles. If you view them in person, it’s obvious that they are much more heavily padded than the Pro/S-Works models, and I believe one of the major reasons why the design of this saddle works is the low profile padding. I find less to be more since less padding often provides greater support, rather than that uncomfortable ‘squishy’ feeling you get from softer, thicker padding. In essence, the cheapest (and only) Power I would consider would be the Pro model. The Comp and Expert simply don’t offer the same support as the Pro.

Now obviously I’m not suggesting that the Power will work for everyone, I’m more recounting  my experiences and opinions. The only way to know for sure would be to try it yourself. If you like the (old) SLR range of saddles, and dislike the Fi:zi:k snake and chameleon range, then (based on my experience) I would definitely give the Power range a test ride.

Saddles are not a one size fits all item, but I wouldn’t be surprised to see the Power saddles feature on more Specialized sponsored teams as time progresses. Despite only two width options being available for the S-Works/Pro models at the time of writing (143mm and 155mm ), I would argue that one of the two options should suit most riders. Just like their insoles, where there are only three options, compared to 3025 possible combinations offered by some competitors (see G8 Performance Insoles), most people seem to get on fine with a ‘stock’ option.

Jagwire Elite link cable review

I’m usually someone who likes black. Black bar tape, black saddles, black bikes etc. I was in such a shock when I received a set of gold cables for review that I forgot to weigh them (sorry, but jokes aside I need to source a new set of scales before I can post weights). Since I won’t be able to post weights, this review will mostly entail the installation and use. If you are interested in the weight, Art’s Cyclery cite a weight of 115g for the (complete) shift kit and 118g for the brake kit. Considering how much housing is supplied, these weights seem reasonable, and are comparable to BDOP’s kit. After cutting, I would suspect that these cables will come in at a similar weight to BDOP’s kit (if not lighter).

First things first, these kits aren’t compatible with full length housing, since the cables rely on splits in the housing to facilitate easy length alterations (unlike traditional housings which can just be cut to length). Having said that, there have been a few documented cases of this kit working with full length rear brake systems (see Krackor’s post). Jagwire do supply plenty of the inner housing, if you’ve got a frame with split internal cable routing, you should be able to make it a fair way into the frames with this inner, which should help in keeping the cables sealed against the elements.

Jagwire's take on the link system

Jagwire’s take on the link system

While Jagwire sell this as a ‘link’ system, these are quite different to other link systems on the market. They feature a pre-lubed inner housing, which the links ‘sit’ over in a head to toe fashion. Jagwire use a standard cable housing under the bartape, which connects to the inner housing either via a barrel adjustor, or a special link (both supplied). I’m guessing Jagwire do this to make internal handlebars slightly easier to install, and to avoid super tight bends with the link section.

Links do not 'bend' around super tight corners

Links do not ‘bend’ around super tight corners

Installation was actually surprisingly pain free, but not as easy as traditional cables. You first need to cut the section which goes under the bartape to length, and tape it in place. This wasn’t too much of an issue, but be careful to check if you’ve got the shift or brake housing as they look similar but are very different (they come labelled).

Jagwire use traditional housing under the bartape

Once you have the bartape section done, you’ll then need to attach the rest of the housing to it. This can be done either with a barrel adjuster, or a special link. If you’re planing on using the barrel adjustors, Jagwire’s approach to this isn’t ideal. If you follow their instructions you’ll end up covering the barrel adjustors with your bartape, as illustrated in the photos below.

How I’ve set up the barrel adjustor, also under the tape

You can avoid this by running the bartape section housing longer (so it extends past the bartape) but this isn’t ideal aesthetically. For this reason I would suggest you avoid the barrel adjustor. The special link they supply sits much nicer under the bartape and provides a smoother transition from regular housing to link housing.

Alternative to the 4mm barrel adjustor

In terms of judging housing length, if you cut the inner housing cautiously this kit is actually quite forgiving, in that you can insert/remove links over the inner housing. When I installed this kit, I left the inner housing slightly too long so it extended past my cable stop, which is aesthetically not ideal, but means I can add links if I accidentally removed too many (which I have a tendency to do). The weight of the inner housing is pretty negligible, so I would rather be safe than sorry when cutting.

I've left some excess housing uncut to allow me to lengthen the cable, if needed.

Out on the road the shifting was smooth, rivalling that of the polymer coated cables from Shimano. Compared to the cables found as original equipment of lower-mid range bikes these are definitely an upgrade, undoubtedly a level above the cheaper options from Jagwire. Even with the tight bend created by my 36cm handlebars I still experienced slick shifting, with no hint of cable friction.

The black coating on the cables no doubt aims to reduce friction, but can also improve the cosmetics of certain externally routed frames. Most frames these days have internal cable routing, so this is a moot point. However, for those who prefer externally routed cables, the black coating does help the cables ‘blend’ in more.

No, it isn't my poor photography, the cable really is black. Jagwire also supply a seal to use on the rear derailleur housing to keep grit out of the cable

Jagwire supply some rubber frame protectors you can slide over the links. Shrink wrap is a lighter alternative, but it’s nice to see details like this included in the kit. Also supplied are some clips to clip different sections of housing together, making it easier to achieve a clean look.  I found the hardest part of making the cabling look ‘clean’ was finding the optimum length, I couldn’t decide if I needed that extra link or not. In the end I decided to include it, though it’ll probably look cleaner without it.

The compressionless housing also helps in obtaining a tidy front end, you can shape the housings a lot more than with traditional outers. Having said that, the housings do shift around a fair bit, which is probably why Jagwire supply clips to help keep them from moving too much.

Apart from gold (and black), the housings are also available in silver red and blue allowing some customisation. I’d say all of the coloured options (red, blue, gold) are quite eye catching, and would look great on a suitable bike.

If you’re in the market for a lighter alternative these are certainly worth looking into. They’re no harder to install than traditional cable housings and certainly perform just as well as the stock Shimano cables. PowerCordz, and other designs will be lighter, but possibly more hassle. I would consider these cables to represent a nice compromise between outright weight and ease of installation. Perfect for those who are a little intimidated by more complicated systems, or simply want an easier system to install.

To conclude, these cables represent a nice aftermarket customisation for your bike, and are a significant upgrade over lower end cables. If you like the looks and weight reduction offered by link housing systems these are definitely worth considering, particularly if you’re intimidated by the complexity of other systems. Most Weightweenies are probably happy to spend a little extra time fitting lighter systems (or have a mechanic do it for them), so this is more of a ‘middle ground’ giving some benefits of compressionless link housing, while retaining the simplicity of traditional housing.

BDop DIY Alloy Road Wheel Kit LT

There are a few websites offering DIY style wheel kits, they supply the rims, hubs spokes etc. for you to build yourself. Recently, BDop Cycling has begun to offer a DIY kit designed to offer a light alloy clincher wheel at an affordable price.

Like the cables that I reviewed earlier, the packaging for these wheels was also very plain – a simple cardboard box.

BDop packaging is plain

You may notice a dent in the upper right hand corner of the packaging. I was a little concerned about this when I was opening the box. However, BDop pack the kit very securely, with plenty of bubble wrap for protection. I was pleased to find that the sorry state of the exterior cardboard was not reflected in the internal contents.

Inside the cardboard middle section were the hubs, spokes and extras included with this kit. BDop do supply a spoke key with this build, which was handy in lacing the wheels, but I found it absolutely useless for tensioning and truing. Call me fussy, but I found the supplied spoke key uncomfortable to grip. I’d recommend the Park Tool SW-20 or SW-0, I personally used a Pillar spoke wrench, also available from BDop. It features good ergonomics, and I’ve never rounded off a nipple with it.

Apart from the actual wheel, you also get a spoke key and rim strips

You will also need to supply your own truing stand and dishing tool. These tools can be improvised, but having the actual tools is a lot easier (Tacx T3175 & T4585 are two reasonably priced but quality tools). I find a spoke tension meter also helps to ensure even tension, but they can be quite pricey (I quite like the Park TM-1, it’s NOT accurate, but it’s very precise – which is more important for even tension).

Tools aside, I found building this kit was quite pleasant, lacing was made much easier by the internal spoke wrench (it grips the nipple well enough so you can insert it directly into the rim) and I didn’t have any weird hops at the rim joint. It personally took me around 4 hours to complete the build, expect less if you’re more experienced, and more if it’s your first time.

Onto the components, nothing jumped out as particularly heavy, or light (for the intended purpose of the kit). The most notable thing I found was that the front QR skewer had the logo printed upside down (if you like to mount the QR skewer pointing towards the rear wheel). The front QR weighs 50g, and the rear weighs 55g. They’re heavy but do a decent job of clamping the wheel.

Novatec logo printed backwards on front QR

The hubset weighed 303g, with the front weighing 60g and the rear weighing 243g. The rear isn’t particularly light, but the front is (referencing the BHS hubs). Both had smooth bearings out of the box, and a good finish. The rear hub has decent NDS spoke tension – about 45% of the DS spoke tension.

Front hub weight

The rear hub features the ABG (anti bite guard) design. Essentially, it’s a metal strip to prevent the cassette from biting into the freehub. From my past experiences with this model hub it works really well. I’ve had 10 000 km in another wheel using this freehub and the there’s no noticeable notching. I’ve had alloy freehubs which notched after only a few thousand km.

Rear hub weight

BDop pointed out that recently a batch of SL rear hubs were mis-labelled by Novatec, which is why the rear hub in this review didn’t have the SL logo. I asked BDop what the differences between the SL hub and the standard hubs were, in short, the SL hubs have more material machined off, leading to a lighter weight. Since the two hubs look so similar (the SL hub is *slightly* narrower) it’s understandable how this mistake occurred.

Moving onto the rims, my two rims averaged 422.5g, so they’re reasonably light considering the width. They’re lighter (but also narrower) than Kinlin’s XR-22T – 440g. However, they are heavier than Stan’s ZTR Alpha 340 rim which have similar dimensions. I would say the weight is about par.

Just a word of caution, these rims scratch quite easily, I managed to scratch them with a spoke while lacing. This isn’t really a criticism (I’ve had similar experiences with Kinlin rims) but more a word of warning.

Rims scratch easily!

Since the spokes (Sapim CX-Ray) and nipples (Pillar alloy) are fairly well known I won’t write too much about them. All up, the front wheel weighs 581g and the rear weighs 791g (1372g total), without rim tape.

The rim strips supplied by BDop weigh 18g per wheel, they do the job, but if you want a pure weightweenie build, veloplugs are much lighter (amendment: I tried Red veloplugs but the fit wasn’t perfect). The included valvinator stickers were negligible in mass.

Rim strip weight

Scientifically, light wheels may not make you significantly faster, but they can make your bike more responsive and fun (subjectively). There are those out there who swear by aero gains, but I personally am a sucker for light wheels. I found these wheels rode like a light wheel should, they spun up easily and were very reactive to power surges. Stiffness wasn’t a let down either. I’m 58kg and I didn’t find stiffness lacking, and nor did my much heavier 76kg friend. I certainly couldn’t pick the difference in stiffness between the Ksyrium Elite wheels I had in for review earlier, but my heavier friend could – commenting that while stiffness wasn’t lacking, the Ksyriums did have an edge. He goes on to mention, given the weight the stiffness is fine. Given the above, I’d say BDop were spot on when they suggest that these wheels were “designed specifically for featherweight climbers”.

Towards the end of the testing month, I began to conclude that this kit would be great for a budget minded weightweenie who likes to tinker with their bikes. While some sites recommend that your first wheelbuild should be a sturdy wheel with lots of spokes (easier to bring into true), I can’t see why someone building wheels for the first time would struggle with this kit. The rear lacing pattern can be a challenge, but that’s a problem with any crossed wheel. If you sit down and look at a few diagrams/wheels you’ll be able to work it out. Perhaps the biggest advantage (and drawback) is that you don’t need to calculate spoke lengths. This is a skill I would recommend learning sometime, but it’s nice to know that the supplied spoke lengths are correct.

If you’re someone who likes brand name or boutique products this kit probably wouldn’t appeal to you (seriously, why are you still reading this review?). However, like the cables, if getting excellent performance for the price is important to you then these wheels are a good choice. They’re an excellent set of light alloy clinchers for a lighter rider (regardless of price). I must add, that you can get much lighter carbon wheels, especially if you go tubular. Having said that, carbon and/or tubular wheels may not be a good option for everyone, and so I would still be inclined to recommend this build kit.

Post Scriptum: After this review BDOP have updated this kit to feature straight pull spokes and hubs, rather than conventional J-bend hubs/spokes. I expect this choice of hubs to better compliment this kit, as the larger flange spacings suggest stiffer wheels. I was impressed with the initial configuration, and this new configuration appears better on paper. Should you break a spoke, sourcing a replacement spoke from BDOP shouldn’t be an issue.

BDop Elite Road Cable Kit Review

Cables can be an important consideration of your next build, a bad set of cables often means poor shifting quality and spongey brake lever feel. Having said that, the stock cables from Shimano and Campagnolo are often decent choices, with low friction and easy set up, but are there other viable alternatives? Over the last month, I’ve had the opportunity to install and test the BDop Elite Road cable kit.

The BDOP Elite cable kit arrived in a no fuss cardboard box.

The BDop Elite cable kit arrived in a no fuss cardboard box.

Unlike many brands, the BDop cable kit doesn’t have fancy logos adorning its packaging, rather a simple cardboard box with the website, and a small label. There isn’t too much to mention with the packaging, other than it was packaged well with plenty of bubble wrap

For once, I didn’t have endless instruction manuals in all the languages known to man to throw out before I started my build. With the unboxing relatively plain – no werid warnings to announce, I moved onto getting some weights:

Complete brake housing kit weighs in at 92g

The compelte brake housing kit weighs 92g, with the outer housing weighing 44g, the cable weighing 47g. The inner housing had a mass of 1g (pretty negligible considering I only used half of it).

Also included were some ferrules and cable crimp cap ends. Moving onto the shift cables, the housing set weighs 92g (like the brake set), with the outers weighing 52g and the cables weighing 38g. Ferrules and crimp cap ends were also included for the gear cables.

When cutting the outers, some of the yellow kevlar sheet becomes exposed, leaving a ‘fluffy’ cut. It looks messy, but it’s hidden by the ferrules so I wouldn’t call it a design flaw. You can file it off if you’re super pedantic, I didn’t bother. On the note of cutting, I didn’t need an awl tool to pry open the outers after I made the cut (I usually need to).

BDop claim that these inner cables don’t fray when cut. I didn’t manage to fray these cables while cutting, but using some spare cable from the FD to test, I was able to fray the cut end relatively easily by poking a few things with it. The uncut end comes with some sort of ‘tip’ to stop it fraying, which I found handy when I was poking around he internals of my frame. My advice there would be to not remove these cables once cut, if possible, and to avoid poking things with it once cut.

Most frames, including the one I installed this kit on (Swift Ultravox) have internal cable guides to aid in installing new cables. If your frame does not have these guides then the internal routing might be trickier, but fear not, as these cables have magnetic properties. I was able to replace the internal cable guides I have in my Swift using fridge magnets to direct the gear cable through the ports, and then sliding the replacement guides on over the top. I would comment that installation was a breeze, definitely no harder than standard cable installation.

I’m using 38cm (outside to outside) handlebars coupled with Shimano 11 speed shifters, which creates a fairly tight radius between the hoods and the tops for the cables to bend around. I have seen tighter bends on some internally routed bars, but I would suggest my shifter/bar combo still results in the sub-optimal cable bend. In spite of the tight bend, I did not experience sub optimal shifting or braking performance – suggesting that friction in this bend was minimal. I didn’t have too many other tight bends in my build, and there was plenty of leftover gear cable housing for the rear derailleur. I’m not sure if there’s enough housing for a full length build though (there should be enough for the brakes, not 100% convinced there will be enough for the gear cables, please check with BDop before purchasing).

These cables did stretch ever so slightly in the first few weeks (they claim to be pre-stretched). The amount of stretch was very minor though, and required only a slight turn of the barrel adjuster to compensate.

In conclusion I haven’t been disappointed with the BDop Elite cable kit. To be perfectly honest, they don’t feel too different from the stock Shimano Dura Ace cables. However, when factoring in the price these do become an attractive proposition ($39.99 USD). If getting similar performance for a lower price is attractive to you then I would recommend these cables.

2016 Mavic Ksyrium Elite Review

The Mavic Ksyrium Elite are one of the ‘old guards’ of the Mavic lineup, with the first wheels to bear the ‘Ksyrium’ name dating back to 2000. 16 years later the Ksyrium Elite rims have gotten lighter and wider, with the current iteration featuring 17mm internal rims and a wheelset weight of 1583g.

Weight - front

Weight – front

1583g for an alloy clincher is hardly impressive these days, and I suspect that heavy spokes and hubs are to blame. With a recommended retail price of 639 euros these wheels are hardly cheap, especially considering the custom build options available. They can generally be bought a bit cheaper online. However unless you find a super crazy clearance deal, they’ll at best be on par (price wise) with a custom build.

Weight - rear

Weight – rear

The supplied skewers came in at 60g (front) and 63g (rear), considering that you can get a skewer set for around 50g these are quite heavy, but they do clamp the wheels well. The supplied tubes were 82g and 87g, not superlight but lighter than what I was expecting (100g). The tyres were 211g (front) and 217g (rear) which I consider respectable, given that they’re 25mm wide. It’s interesting to note Mavic recommend a tyre width of at least 25mm for these wheels.

In terms of serviceability, the bearings are user adjustable and the tool (Mavic M40123) is provided. This tool also doubles as a tyre lever and a spoke key, so it’s a handy addition to the package. It’s certainly a good tool to have in the back of your pocket as it’ll cover most adjustments you’ll want to make on the road. Speaking of spokes, Mavic’s proprietary spokes can be sourced from your local dealer, or some online stores. However, they are very expensive, costing quite a few times more than either Sapim CX-Ray or DT Swiss Aerolight spokes. This does detract from the overall appeal of these wheels, but if you rarely break spokes it’ll only be a minor annoyance now and then. If you are hard on your equipment I would keep this in mind before buying.

2x Mavic M40123 are supplied with the wheels – a thoughtful addition

The first thing I noticed about these wheels was how well they roll. I wasn’t expecting anything special from the Mavic hubs, but they rolled incredibly well. The freehub engagement isn’t as quick as some other hubs, but out on the road I didn’t notice this too much. On this test sample, a few of the aero spokes were wound up. Untwisting the spokes with an aero spoke holder didn’t result in the wheels going out of true so it was an easy fix. Still, something like this should be picked up in the quality control.

Mavic Ksyrium Elite WTS 2016

Mavic Ksyrium Elite WTS 2016

I was quite disappointed with the tyres and tubes which make up the WTS. Put bluntly, the tyres were pretty average. They were decently supple, but I had a sensation that the tyres were a little ‘dead’ under acceleration. Perhaps these tyres were designed to be more of a durable, high mileage tyre, rather than a super soft and light race tyre but I do think there are better tyres for either market. In essence, I wouldn’t describe the tyres as something that adds value to the package, rather they’re something to be replaced when the opportunity arises.

Mavic ISM 4D rim

When I did replace the tyres with something nicer (24mm Vittoria Open Corsa SR) and swapped the butyl tubes out to latex, the wheels felt much better. I no longer had the ‘dead under acceleration’ sensation, and this package responded much better to surges in power. As noted before, these wheels do roll well with the stock rubber, but there was a sensation of ‘rolling forever’ with the above tyre/tube changes. On flatter rides, while these wheels won’t offer an aerodynamic advantage, they don’t feel slow. However, these wheels felt most at home in hillier terrain.

From a weightweenie perspective, these wheels are disappointingly heavy – it isn’t hard to build a 1350~1400g wheelset for this price (and even lower if you’re willing to buy carbon tubulars), but never once did these wheels feel sluggish on the climbs. They certainly feel much lighter than their (almost) 1600g weight might suggest. When climbing, these wheels were stiff under power and accelerated well. Coming down the other side there was no flex when cornering, and the bike never felt skittish with these wheels. The braking surface was well machined, and the braking was always smooth and consistent with the stock Shimano pads – they’re certainly a step above rims made by Kinlin. When I was just riding along I didn’t notice this, but down some steep, technical descents I really appreciated the consistent braking on offer, leading to greater confidence and (marginally) faster descending.

Summing up, these wheels performed solidly in a variety of conditions, particularly in hilly terrain. The tyres might suffice for solo training or commuting, but are less suitable for racing or harder group rides. For the price, the frugal shopper might be a bit underwhelmed with the on paper specs, but they don’t disappoint out on the road. Still, I wouldn’t pay the RRP for these wheels – shop around for a discount.

The author would like to acknowledge that these wheels were supplied by Starbike for the purposes of this review. The RRP (recommended retail price) was correct as of 26/12/15

Vittoria Rubino Pro 3 review

Vittoria Rubino Pro 3

Vittoria Rubino Pro 3 tyre – not to be confused with the standard Rubino 3

Most seasoned cyclists have a favourite tyre of choice, a tyre which they can rely on, representing the the ‘best’ compromise of all the characteristics they desire. I’m aware that many of us are not overly fussed with durability, and desire the best road feel. However, for myself, I want to be able to get through a year on one set of tyres. I want a set of tyres that can handle all four seasons, be durable enough for winter and fast enough for summer. Previously, this tyre was the Continental GP4000S. It had decent puncture resistance, and was quick enough for my fast group rides. Some say it feels a little ‘dead’, and yes it is a little dead compared to tyres such as the Vittoria Open Corsa, but it wasn’t any worse than tyres with similar durability. Now that Continental have updated this model, I felt the need to experiment a little with other tyres. Over the past year, I’ve been testing the Vittoria Rubino Pro 3 tyre, and it’s making a strong case as a solid alternative to the GP4000S.

Durability is an important consideration for me. While I don’t rack up the same amount of kilometers that the pros do, I train fairly consistently and do want an element of ‘set and forget’ so I can focus on my training. What this means is that I don’t want to be replacing tyres every couple of months, I want at least 6000km from my tyres. The Rubino ticks this box for me, keeping in mind I weigh 60kg so your tyres may wear slower/faster depending on how much you weigh. My point is, these tyres are certainly more durable than the Continental GP4000s tyres, which I usually expect 4000-5000km from. I’ve included some photos of the conditions of the tyres at 3000km. A few cuts have made their way through, but nothing too drastic, they’re certainly fairing better than I would expect from a set of GP4000s. Having said that, it isn’t in the same class as the Maxxis Refuse or Continental Gatorskins. I wouldn’t class this tyre as a daily hack commuting tyre, the casing is a fair deal softer and I find that I puncture much more often than I would expect than with the above mentioned tyres.

While it may not have the same low rolling resistance as the GP4000s tyres, the Rubino Pro 3 tyres are a good deal cheaper, they can often be found for around half the price of the new GP4000s II. This cost factor may not be such a consideration for some, but it’s always nice to save some money, provided the product performs just as well. What do I mean by this? Well, despite being slower, the Rubino Pro 3 maintains a decent level of responsiveness and doesn’t rob the bike of all life, like some tyres can (e.g. Maxxis Refuse). In fact, in terms of feel, the Rubino doesn’t feel any slower than the GP4000s, it’s only when I look at my power data and finding I’m consistently having to put out (slightly) more power for the same times up my local climbs did I begin to suspect something was amiss. It should be noted that that the difference is within error (3w difference in a 300w effort). However, more scientific and conclusive tests (such as Crr tests by WMW on the weightweenies forum) have ranked the Rubino Pro 3 slower than the GP4000s.

I know some would be immediately turned off by the fact that the Rubino tyres test slowly, but as a training tyre it is acceptably fast, especially considering the high levels of feedback given by the tyre. It’s not anything groundbreaking, and there’s substantially less grip than a pure race tyre (I’ve worked that out the hard way…). However, the Rubino Pro 3 does offer a huge increase in puncture resistance and durability, and demonstrates that durable tyres don’t necessarily have to be ‘dead’. As a training tyre, which might get raced on (as a spare wheel on race day) it offers acceptable speed, and dependable puncture resistance.

Flexing the casing with my hands reveals a decently supple casing. Again, it’s not very soft compared to high TPI open tubular tyres but it does offer a similar degree of flex compared to Michelin Pro 3 race tyres. This correlates well to how they feel on the road, around the same ballpark as the Michelin Pro 3 tyres.


Condition after 3000km, note the slight flat spot starting to form

If I had to use only one word to describe this tyre, that word would be ‘compromise’. It represents the middle ground, a reliable training tyre, which you can set and forget on your training wheels. If you don’t have the luxury of having multiple wheels, or the time to swap to a nicer set of tyres before race day, I’d be more inclined to recommend the GP4000s. If you’re not racing, or have a dedicated set of race wheels, the Rubino Pro 3 can do everything you ask of it in-between races. Whether that’s a long solo training ride, or a fast group ride the Rubino Pro 3 offers an excellent blend of durability and liveliness.

In my humble opinion, I see the Rubino tyres as a great training tyre. However, it isn’t for everyone. It’s durable and offers good feedback, but by no means is it fast compared to out and out race tyres. If you’re able to accept the durability of the faster race tyres then these tyres don’t make a particularly strong case. It’s only when you find the durability of these race tyres lacking do the Rubino pro tyres make a strong case. What they don’t have in pure speed, they make up for in durability. As a high mileage training tyre, this has got to be one of my favourites.

Giro Trans E70 review

For 2015 Giro updated their popular Trans shoe with a slightly different carbon sole and new designs. I’ve been riding these shoes for the past 3 months, here’s my opinion on them.

Giro Trans E70 shoes

Giro Trans E70 shoes.

Still featuring the same Easton EC70 carbon sole, the Trans E70 now has replaceable heel walking pads. The actual design of the sole has varied slightly, and the upper has changed from a glossy to a matte finish.

Different carbon sole designs. On the right is the new E70

Different carbon sole designs. On the right is the new E70.

The ratchet mechanism has also been redesigned for greater aerodynamics. However, Giro don’t make any claims as to how much more aerodynamic it is. It features a lower profile design which looks neater, but doesn’t function as well as the previous design.

New low profile ratchet found on the new E70 design

New low profile ratchet found on the new E70 design.

The new low(er) profile ratchet design I feel is inferior to the older, higher profile design. When releasing the ratchet, the new design only releases one or two buckles at a time, whereas the old one can release all the buckles in one go. When tightening, the old design can tighten anywhere between one and three buckles in one sweep, contrasting to the new design which can only tighten one buckle per sweep. This means the new design isn’t as fast when you’re trying to make on the fly adjustments. I personally value faster on the fly adjustments in contrast to aerodynamics, so I fitted the old ratchet mechanism onto my new E70 shoes.

Old ratchet design isn't as aerodynamically slick, but is faster to use on the fly.

Old ratchet design isn’t as aerodynamically slick, but is faster to use on the fly.

As you’re probably guessing, not much of the actual fit has changed much. The shoes still feature Giro’s Supernatural Fit Kit, with Aegis topsheet. My only criticism of the Fit Kit is that the Aegis topsheet looks a little cheap next to the X-static top sheet found in the higher end models, but it works just as well.

Two footbeds side by side, on the left is the Aegis topsheet and on the right is the X-Static sheet.

Two footbeds side by side, on the left is the Aegis topsheet and on the right is the X-Static sheet.

I usually find I have to swap the insoles of my shoes with Specialized Body Geometry SL insoles. However I’ve been pretty happy with the Supernatural Fit Kit, it offers the right amount of arch support for me and has a similar metatarsal button design. For reference I use a Red+ (low arch) Body Geometry insole, and I find the orange arch support (medium support) offered by the Supernatural Fit Kit similar in terms of arch support. You can obviously customise the Fit Kit to your needs. It’s a smart idea allowing Giro to supply a one size fits all insole, removing the complexity and added cost of having to buy an aftermarket insole to suit your new shoes.

The reverse side of the two footbeds, The X-Static footbed  (right) has black inserts, which prevent the footbeds from slipping and increases the stiffness of the footbeds.

One slight difference in the fit of the E70 vs the original Trans is in the heel cup, the E70 has a much more supportive heel cup. The heel cup insert of the two models feels the same, however the E70 features more padding around the heel, which helps keep the heel planted.

Apart from the visual differences, the E70 (right) has a more supportive heel cup.

You’ll find that Giro’s sizing is a little larger than most companies. For reference I run a size 42.5 Shimano and Bont, but I find the 42.5 a little roomy in the Giro shoes. I find the 42 a better fit, it’s similar to the 42.5 Bont shoes lengthwise, but doesn’t have the same wide toe box, which suits my narrow feet. In terms of Shimano I find the Giro 42 in-between the Shimano 42.5 and Shimano 42. I’d advise trying on half a size smaller than what you normally wear. Giro do have a shoe size conversion tool, which I found useful, especially the US Mens flavour if using Bont shoes as a reference point (size 42.5 Bont shoes are size 9 US, which correlates to a 42 Giro shoe).

Giro Trans E70 offers a smart looking shoe

Giro Trans E70 offers a smart looking shoe.

Another interesting thing to note is the low stack height of these shoes, a claimed 6.5mm. While this is still almost double the stack height of my regular Bont shoes (3.8mm) they’re much closer than most other brands (e.g. Spiuk). Despite the thin sole these shoes are still plenty stiff, I found them to be of similar stiffness to the higher end Giro Factor and other shoes from competitors (e.g. Bont A1, Shimano R241). These shoes are slightly stiffer than Shimano R170 shoes and Specialized Expert Road shoes.  I determined shoe stiffness by trying to flex the shoes in my hand (not very scientific, I know), but I find most shoes that flex a little, or not at all in my hand are adequately stiff on the road.

The Giro sole isn't as thin as the Bont soles, but is about half the thickness of the Shimano R241 soles (pictured left)

The Giro sole isn’t as thin as the Bont soles, but is about half the thickness of the Shimano R241 soles (pictured left).

On the note of the sole, like all carbon fibre soles they scuff easily, so if you want to keep them looking pristine you ought to be careful where you step. Things like rocks etc can do a lot of aesthetic damage.

Carbon soles are easily scuffed

On the topic of aesthetic maintenance, the matte white finish is particularly hard to maintain. Road grit happily sticks to this surface so you’ll need to be vigilant, regular hot water and soap isn’t enough to keep these shoes looking clean.

Don't kick anything with these, the toe section is easy to scuff and make dirty.

Giro do offer other colour options (such as high vis yellow and black) which may be easier to keep clean. But if you’re happy to put the extra effort in cleaning, the white shoes do look the best of the lot in my opinion.

Just like white bar tape, white shoes are hard to keep pristine

Just like white bar tape, white shoes are hard to keep pristine.

Cleaning gripes and ratchet swaps aside, I’ve been extremely pleased with the performance of the Giro Trans E70. Once worn in they’re a super comfortable shoe which are stiff and reasonably light. They offer a supportive footbed, and heel cup. Not having to buy an aftermarket footbed is a huge bonus, and really adds to the value of these shoes. The closure system, despite being simple, secures the foot well and evenly distributes the pressure. They might not look as fancy as some of the newer Boa or lace up shoes, but I’d be inclined to say they perform every bit as well.

Sigma ROX 10.0 Review

Over the past few months I’ve been testing the Sigma ROX 10.0. It’s a solid device with an interesting feature set, namely the inclusion of “breadcrumb” navigation. Not to be confused with the turn by turn navigation featured on more expensive models from competitors (eg Garmin edge 1000) breadcrumb navigation is a simple representation of a path you should follow. A useful feature, but does the rest of the package stack up?

Unboxing the Sigma ROX 10.0

Unboxing the Sigma ROX 10.0

The short answer would be yes. It does everything you would expect a GPS computer to do at this price point (e.g. ANT+ compatibility, screen customisation, etc.). You certainly are getting a lot of GPS computer for your money.

In the box: manuals, bike mount and Data Center installation CD.

In the box: manuals, bike mount and Data Center installation CD.

However the user interface is a little cramped, it feels like Sigma are trying to pack too many features onto the small screen. This can be a little overwhelming initially, particularly if you’re coming from a Garmin 500, but it’s no more cramped than the Polar CS600. I would prefer a larger screen size, but I can understand why Sigma would want to spec a smaller screen size (e.g. cost, size). While I’m complaining about the screen, it scratches easily so I’d be careful about leaving it upside down (it happens more thank you think). On the plus side, the screen is curved so you’ll never get the sun reflecting in your eyes (a problem I’ve encountered with devices from other brands with flat screens).

While I’m on the topic of the Polar, just like the Polar, the Sigma comes with it’s own computer software (Sigma Data Center). While not quite as analytical as Golden Cheetah it’s nice to see that Sigma care about post ride data analysis.

Sigma Data Centre Dashboard

On the note of post ride data, Sigma don’t play nice with Golden Cheetah. You can export your data files, but the export formats available aren’t compatible with the current versions of Golden Cheetah. It’s a little annoying, especially if you’re addicted to Golden Cheetah. If you don’t know what Golden Cheetah is, or don’t have Golden Cheetah this could be the perfect unit for you. For those tech savvy readers, Sigma does export as GPX, which *should* work with Golden Cheetah, but they follow a different protocol than what’s accepted as the standard. Long story short, Sigma don’t export the time ridden in the correct format, and when Golden Cheetah attempts to read the file your duration is 0:00, not very useful if you want to analyse your ride with Golden Cheetah.

Importing rides into Golden Cheetah

Sigma Data Center does allow you to upload your rides to Strava. It’s quick and easy to set up by clicking “Menu” tab and selecting “Share Data”. Just follow the prompts and log into Strava as you would on their website. Once set up you simply have to click “Share Data” to upload your rides to Strava. After a brief delay while the cloud does its magic your ride appears on Strava.

I’m not too critical of Sigma’s lack of compatibility since their own Data Center software should cater to the needs of most people. While it may not be as detailed as Golden Cheetah, Data Center does include the basics:

Sigma Data Center provides a useful summary of your rides

Most importantly, Data Center allows you to keep a training diary. It’s a nice touch, you can record details about your training partners, feeling/form, training type and an evaluation of the effectiveness of your training. If you’re dedicated you’ll love this feature, but I find myself being lazy and not filling the diary out. If you’re serious about your training you probably already keep a diary. Even if you already do keep a diary, this feature is useful as it integrates your diary and your data. If you’ve never kept a diary before Data Center provides an easy way to start, especially if you’re not sure what you should be writing in it.

It may be a little gimmicky for those of us who are just riding for fun. But if you smashed a PB or rode your first double century, or placed well in a road race it makes it a little easier to keep track of those milestones. If you’re not into keeping diaries but would like to track how you’re responding Sigma has a useful feature which shows how your average heart rate is changing over time. If you’re overtraining you may notice your average heart rate dips or spikes. You can also keep track of how many “hard days” you’ve had, or when your last easy day was.

Data Center keeps track of your training load

You can also plan your training using data center, by plan I mean you can plan your routes. It’s useful, particularly if you’re visiting a new city, or when you plan on exploring an unfamiliar part of town. The mapping is fairly accurate, Sigma decided to use open source mapping for this device (OpenStreetMaps). Making a route is pretty straight forward. You simply select the “create route” option in the top right corner (it’s the squiggly line that’s highlighted):

Once you’ve selected the “create route option” simply click on where you want to start (indicated by the green marker) and where you want to go (indicated by a red marker). Data Center will find a route for you, from green to red.

Data Center will create a route for you. Simple, isn't it?

Like all software sometimes Data Center has it’s moments. Sometimes, Data Center won’t recognise certain roads, if you try to create a route along the missing road Data Center will give you the following error:

Data Center error message

Fear not, because Data Center also allows you to manually enter your route, using the “create linear track” option. It’s the straight arrow next to the curly arrow (which is the “create route” option). It’s more time consuming, but it works. You can also change the settings of Data Center to avoid main roads, or to take backstreets but  sometimes Data Center may direct you along certain roads which may not be to your liking. You can override this by manually creating a linear track. The yellow markers are where I’ve created a linear track.

Apart from navigation, you can also familiarise yourself with the profile of a ride. You can access this information by clicking the “Altitude Profile” button (the two hills in the top right hand corner). Your course profile will be displayed on the bottom of your screen.

Data Center also displays a course profile.

Data Center also displays a course profile.

All these features are quite useful if you’re new to or unfamiliar with an area. All this information can be accessed on the fly on the ROX 10.0, albeit much less detailed and crammed onto a smaller screen. One drawback of the ROX 10.0 is you cannot create new routes on your device whilst riding (and even if you could it would be really painful on the small screen). However, it does have a “take me home” option, which essentially directs you back home by reversing the course you have ridden. It’s a useful last resort, but not particularly handy if you took the scenic route before you got lost. It’s better than nothing, but since most of us own smartphones with maps of some form or the other I recommend using the phone if you’re lost, particularly if you have taken a few detours along the way (the ROX 10.0 will direct you back along the same detours).

The Sigma ROX 10.0 is a feature packed computer, especially at this price point. On paper, these extra features would be the ROX 10.0’s greatest strength, and really set it apart from competing units. However, one can also argue that it’s greatest strength is also it’s greatest flaw. The screen size limits the usefulness of some of these features, particularly the navigation, though having some “breadcrumb” navigation is so much better than none at all. I do applaud Sigma’s ambition in packing the ROX with all of these features, and to be fair GPS computers at this price point all have a similar screen size. A little more refinement could make this unit a market leader. As it stands the ROX is a solid unit, it certainly trumps devices like the Garmin Edge 500 in terms of features, but lacks in the user friendliness department.

Pros: Data Center is well thought out, has more features than any other device at this price point.

Cons: Screen size limits functionality
