SRAM Eagle SL X-Sync 2 DM Chainring The X-Sync 2 chainring is a product of SRAM's drivetrain engineers studying the performance and wear on thousands of X-Sync chainrings. They subjected every size of chainring to environmental and mechanical tortures, abuse and neglect, in both real world and lab testing. They wanted to create a chainring that would improve the Eagle drivetrain's performance in all conditions. The new X-Sync 2 chainring provides increased chain retention, decreased friction, and reduced noise and wear. Features X-Sync 2 chainring design increases chain retention, wear life, and reduces friction and noise Forged and machined aluminum provides a strong and durable product SRAM direct mount design is clean and functional Available sizes:32t, 34t, 36t, 38t Available options: Black/Gold, Black/Grey Designed to be used with SRAM Eagle 12-speed chains | Sram | Eagle Sl X-Sync 2 Dm Chainring | Black/gold | 32Tooth, 3Mm Offset | Aluminum
