SRAM X-Sync 104 BCD chainring

The radical new look and feel of Srams X-Sync? 2 Eagle? chainring is a direct result of SRAM drivetrain engineers studying the performance and 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 Meters Specifications: - Weight: 48 g
