SRAM Chainring X-Sync Eagle 34T 104BCD Alum 12 Speed Black

SRAM Chainring X-Sync Eagle 34T 104BCD Alum 12 Speed Black

The radical new look and feel of SRAM's 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. They 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:

• Compatible with 11- and 12-speed drivetrains.
• Designed specifically for Eagle chains and drivetrains.
• X-SYNC™ 2 design increases chain retention and wear life, and reduces friction and noise.
