SRAM X-SYNC 11 Speed Argon Grey ChainringsAll set for clocking up the miles, this chainring gives you the highest level of performance and durability on your road bike adventures. It features a hard-wearing aluminium construction, which makes it perfect at handling all the intensity that comes with long days out on the road. SRAM has also put this version through a CNC-machining process which shaves off any excess material. This allows you to benefit from its fantastic strength without adding any unnecessary weight to your ride.

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 chain rings 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.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
