The radical new look and feel of the SRAM X-Sync 2 30T DM 3mm Offset MTB Chain Ring 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 drivetrains 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. Key Features: - Material: Aluminum- Mount: SRAM direct mount- Offset: 3mm (for 12x148mm bikes)- Chainline: 51mm- Warranty: 2 years
