Sram X-sync 104 Bcd Chainring Black 36t

The radical new look and feel of Srams X-Sync? 2 Eagle? chainring is a direct result of SRAM drivetrain engineers studying the performanceand wear characteristics of thousands of X-SYNC? chainrings. Sram subjected every size of chainring to untold environmental and mechanical tortures, abuse and neglect, in both lab and real-world settings, to come up with a chainring that would augment the Eagle? drivetrain?s performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagle? chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.Features:- Designed specifically for Eagle chains and drivetrains- Compatible with 11- and 12-speed drivetrains- SRAM X-SYNC 2 design increases chain retention and wear life, and reduces friction and noise- Material: 7075-T6 forged and machined aluminum, anodized- Bolt Circle Diameter: 104 BCD- Speeds: 11-/12-Speed- Compatibility: SRAM XX1 Eagle and SRAM XX1 Power MetersSpecifications:- Weight: 48 g
