AXS Web analyses your ride files specific to shifting, gear use, power zones, and tyre pressure, so that you can quickly and easily learn more about how your bike is working for you and consider adjustments. X-Sync: SRAM X-SYNC 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. Accept no imitation. Orbit: Orbit technology is an innovative form of derailleur motion control. It utilises silicon fluid as part of an elegant and ultra-lightweight damper system. Compared to a standard friction clutch system, Orbit technology places no additional resistance on the rear derailleur's spring when under slow or light movement. This means easier shifting and rear wheel removal. And while riding, the fluid damper reduces chain bounce. It's rock-solid reliability for both 1x and 2x systems.Manufacturer's Part Numbers: 00.7518.121.001 Grey Short Cage Max 33t 00.7518.136.000 Grey Medium Cage Max 36tBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
