GRAVEL Designed with the unknown in mind, the Rutland takes the guess work out of selecting the right tire for the ride. Ramped, tightly spaced center lugs reduce rolling resistance while larger, more spaced-out shoulder and transition lugs provide grip in loose conditions. HOW IT WORKS - Center lugs are large and widely spaced for braking and acceleration grip, and ramped to lower rolling resistance. - Transition lugs are spaced out to shed mud; siping conforms to the road surface for increased traction in corners. - Side lugs are staggered to provide traction in more aggressive turns and on loose surfaces.

The radical 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 Eagle chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.
