SRAM/Truvativ X0 X9 Chainring

Yes, this chainring is specifically engineered for 10-speed mountain bike drivetrains. As long as your crankset utilizes a 104mm BCD 4-bolt mounting pattern, it will integrate seamlessly.

This chainring is optimized specifically for 10-speed chains and shifting ramps. While it might physically bolt onto other cranksets with a 104mm BCD, the tooth profile and shift pins are designed for the precise spacing of a 10-speed chain, so using it with other speeds may result in poor shifting performance.

No, this product includes only the chainring itself. You will need to reuse your existing chainring bolts or purchase a new set that matches your specific crankset.

The over-shift pin is a critical feature that helps guide the chain onto the teeth during a shift. It ensures that gear transitions remain smooth and precise, even when you are shifting under the high torque loads common in mountain biking.

This is an outer chainring, designed to be the largest ring in a multi-ring setup. It features the necessary ramps and pins to facilitate shifting from the middle ring up to the big ring.
