This highly efficient narrow/wide chainring will grip the chain perfectly, prevent chain drops and will increase confidence you have in your bike's drivetrain.
This version of this chainring is compatible with the direct mount engagement on the SRAM GXP and BB30 long spindle cranksets with a removable spider.
Now with performance enhancing chain retention technology. Burly enough for DH Racers and Dirt Jumpers, yet light enough for XC/singlespeed.
Single Rings are machined from 7075-T6 aluminum and tested in some of the most punishing riding terrain. Built to last!
Why buy an Oval Chainring?
An oval chainring will provide a significantly more constant torque to the rear wheel. Thereby increasing traction and reducing stalls/spinouts while climbing.
Ovality: 12%-13%, Timing of 115° after TDC (Top Dead Center).
Deep Narrow Wide tooth profiling ensures ultimate chain retention.
