ใบจาน จานรองโซ่ CRING X-SYNC 12sp 38T DM6 สีดำ

The radical new look and feel of SRAM’s X-Sync™ 2 Eagle chainring is a direct result of their 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 pedalling efficiency, while decreasing friction, noise and wear.
