SRAM Force 1 1x11 Speed Cyclocross ChainsetThe SRAM Force 1 Single Speed Cyclocross Chainset is a gamechanger. This chainset has combined all the benefits of SRAM's Force 22 road with SRAM's MTB (mountain bike) technology, X-Sync™, ensuring this chainset is reliable, durable and efficient, whatever the trail brings. The SRAM Force CX1 crankset brings to cyclocross a game-changing upgrade in performance and reliability by combining the durability, simplicity, and efficiency of Srams’s Force 22 road combined with their MTB 1X technology, X-Sync™.RAM X-Sync™ 1X chainrings provide the highest level of performance and durability. The SRAM X-Sync™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain.To provide the best possible performance in muddy conditions, the X-Sync™ chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync™ rings are an integral part of the SRAM 1X™ drivetrain.Features:Arm Material: Carbon arms with forged Aluminium removable spiderTechnologies: X-Sync™, Hidden Bolt configurationFinish: Natural carbon armsWeight: 679g (172.5mm, no BB)Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

We’re talking full-power shifts. Up, down, whatever the trail demands. The benefit of the X-Glide drivetrain is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means you’ll never again compromise your speed and power in unpredictable off-road terrain. Here’s how we did it: TRUVATIV’s crank engineers threw away the old standards and developed a new chainring geometry from the ground up. They precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin—rather than the middle of the chain link—you get double the shift opportunities. No more missed shifts, ever. X-Glide puts you in the right gear, right now.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Named after a famous redwood-covered climb in Santa Cruz, California, the Praxis Works Zayante S crankset is designed to offer incredible value and cutting-edge technology with an excellent range of gearing options & lightweight construction.Lightweight carbon crank arms are incredibly stiff for efficient power transferM30 spindle is compatible with BSA, BB86, 386EVO, BB30, PF30, T47, BBRight & OSBB bottom bracket shells BB's sold separately10/11spd LevaTime II chainrings are cold forged for supreme shift quality & durabilityVersatile modular design can accept 2x or 1x DM chainringsLightweight at just 684g (172.5mm w/ 50/34T Chainrings)Where most cranksets can only be fitted with a small selection of chainrings, the Zayante S is designed with versatility in mind. While equipped with 2x chainrings as standard, the direct mount design can easily be swapped out for a 1x chainring or another 2x combination in a different ratio. Praxis wants you to have control. Add in to this compatibility with pretty much any bottom bracket shell on the market when used with the appropriate bottom bracket, and you have an incredibly versatile crankset that is happy to grace lightweight carbon race bikes or tough steel gravel bikes. The crankarms themselves are hollow forged, which gives them immense strength and stiffness, so you can be sure every watt of power your legs can muster isn't wasn't with flex. Despite this, the crankset is extremely light at just 684g. The M30 spindle also helps to keep weight low and stiffness high.Whereas most chainrings are stamped or machined pieces of aluminium, the Zayante S's chainrings are cold forged from 7075 T6 aluminium and then hard anodized. This unique method creates chainrings that are just as light, but are much, much harder wearing and provide slicker shifting for longer. Further improving the shifting performance is Praxis Works LevaTime II Shifting Technology. LevaTime II Shifting boasts a series of synchronised ramps and strategically placed shift pins to help deliver perfecting every time. Lightweight, stiff, smooth shifting and extremely versatile, the Praxis Works Zayante M30 DM crankset is perfect for riders who want maximum performance without breaking the bank.
