Earlier this week SRAM announced a new 1x groupset, Apex 1. With this new groupset SRAM wants to offer ‘unrivalled value’ and simplicity, which it achieves by trickling down 1x technology to Apex level. SRAM expect the group to be available during June 2016.
SRAM offers shifters for both flat bar and drop bar bikes. The drop bar shifters feature a new master cylinder design, and easier bleed port access. SRAM claim a weight of 344g
The rear derailluer features cage lock technology for easier wheel changes. The long cage design can take an 11-42 cassette and is compatible with both 10 and 11 speed SRAM 1x systems. The cage is made from steel, making the system quite heavy with a claimed weight of 314g
Moving onto the chain and cassette, SRAM are offering a new 11-42 PG-1130 cassette which will apparently fit 10 and 11 speed freehub bodies (11 speed freehub bodies requires 1.85mm spacer). If this claim is true it might mean you can use your older 10 speed wheels with this group. The cassette weighs in at a huge 538g (claimed).
A new chain has also been released by SRAM (PC-1110) which is designed to work specifically with X-SYNC chainrings. SRAM site compatibility with all SRAM 1x groupsets. SRAM use solid pins, with a claimed weight of 232-273g (depending on chain length, SRAM haven’t specified how many links this is for).
There’s currently only a hydraulic disk option, designed around 160mm and 140mm rotors. They can fit either 74mm or direct mount frames.
Finally, the new 1x crankset, branded as s-350 feature a 42t X-SYNC chainring. It features a 24mm spindle and is available in 170mm,172.5mm,175mm crank lengths. SRAM claim a weight of 762g.
I’m personally quite excited by this new groupset, it should see adventure/cross bikes with hydraulic disc brakes coming down in price, which I welcome. I currently don’t see a cable rim brake option for this groupset so I presume SRAM is pushing hard for hydraulic disk brakes.
