Shimano chainrings offer durability and confidence-inspiring performance, and go a long way towards getting a drivetrain back to optimum working condition. - Fits many older Shimano pre-Hollowtech II cranksets with Octalink V2 or square spindle bottom brackets - Middle chainrings from Octalink (Hollowtech I) and square spindle cranksets are not interchangeable with middle rings from Hollowtech II cranksets

Shimano chainrings offer durability and confidence-inspiring performance, and go a long way towards getting a drivetrain back to optimum working condition.

Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains SRAM has ever made. The radical new look and feel of the 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. The longer, positive-rake tooth shape has been designed to work perfectly with Eagle chains to increase chain retention and overall pedaling efficiency, while decreasing friction, noise, and wear. The complete Eagle system—crankset, chainring, chain, shifter, derailleur and cassette—is designed, tested, and proven to deliver the ultimate mountain bike drivetrain. Put simply, Eagle is capable of revolutionizing the ride for all riders on every kind of terrain. - Designed to be used with Eagle chain - Material: Steel

The all new Turbine 11 Speed rings are ready to ride. Completely redesigned from the ground up, these rings shift like nothing else. The Turbine rings are machined from 7075 aluminum, so they are built to last. Rings are CNC'd from 7075 alloy, creating a ring with instantaneous smooth and quiet shifting, even under load. These 2x rings are super stiff at a minimal weight, resulting in a ring that demonstrates sharp and quick shifts while being highly resistant to impacts.
