2 flaws in this crankset:
1. SPACER CONE, THAT GETS INSERTED INSIDE THE AXLE ON THE NONE DRIVE SIDE. The plastic cone is too wide & what ends up happening is that once it is inserted in the BB, it is so tight that once the crankset is assembled and spin the crankset, it will only do 1/2 a revolution, which indicated that the plastic is preventing the bearings from spinning & it even gets worst when you start pedaling, as if the brakes are being applied.
So what you will have to do is take the spacer cone and sand it down w/ a sand paper in the outside to remove the excess plastic. Once you achieve by removing the right amount of plastic, watch it spin freely, the way it should be.
2. COVER PLATE:
The cover plate that is in the non-drive side has so much stress during the pedaling process. The plate is what keeps the crankset whole or intact, (FYI, that pinch bolt that is attached to the non-drive side crank arm does nothing)
so every time your:
== standing up and rocking the bike left / right & your right foot is at
6 o clock and the frame is leaning to the right, at that point you are actually pulling the HEAD plate with your feet, & at that point the head plate & nut end that gets screwed in the axle will separate (it will take time, for me about 3000 miles).
== the other one, is when you're doing a very sharp cornering to the left, and take your body and lean to the right & your feet at 6 o clock.
Luckily when the head plate separated from the nut end, I was on the flats (all I heard as if a coin fell on the ground and I was like, what was that, till 3 block later I noticed the head gone and I thought that the whole thing came loose and fell off, while in actuality, it broke in half). & I was surprised that the
non-drive side crank did not come off for the next 10 miles (please note, the non-drive side crank will come loose and the crankset will come off the frame at some point, so go straight home, do not finish your ride). Can you just imagine if that were to happen on the turns or during a climb.
Also the nut end, will not be a problem removing it inside the axle, you can just take an Allan wrench to remove it.
After this happens, you will not be able to ride your bike till you replace the part. So since this happened, it is safe to say, you best purchase several of these plates, as this will be a REOCCURRING PROBLEM.
Bottomline, if my AX Lightness frame, could accept a Campagnolo crankset, I would do a way with this product, as well as these light components as they are nothing but a headache, even thou light in weight, they either don't function properly or don't function at all, longevity is an issue & not to mention poor quality. In the end you're just throwing money away.
NO offense to the Germans, the idea & concept is great, but there are flaws to the ideas that are not address during the R&D phase, but then again, I believe they are aware of these flaws and just don't care.
