Shimano XT M771 Chainring

No, this specific chainring is engineered exclusively for 9-speed mountain bike drivetrains. Using it with a 10 or 11-speed chain may result in poor shifting performance and increased wear.

You need to measure the Bolt Circle Diameter (BCD) of your crankset. This chainring requires a 64mm BCD, which is the standard measurement for the inner ring on many triple cranksets. If your crankset is designed for a different BCD, this part will not mount correctly.

No, this is specifically designed as an inner chainring. The ramp and pin profiles are optimized for the inner position to facilitate shifting up to the middle ring, and it will not function correctly if placed in the middle or outer positions.

No, this product includes only the chainring itself. You will need to reuse your existing chainring bolts or purchase a new set separately if your current hardware is worn or damaged.

A 26-tooth count is a standard size for an inner ring on a mountain bike triple crankset. It provides the low gearing necessary for climbing steep, technical terrain while maintaining a manageable cadence.
