Shimano XTR M9120 Crankset

No, the XTR M9120 crankset is sold as arms only. You will need to purchase a compatible Shimano direct-mount chainring separately to complete your drivetrain.

This crankset features a 168 mm Q-factor. This measurement is designed to provide a stable, efficient pedaling stance suitable for most modern trail and enduro mountain bikes.

While this crankset is optimized for Shimano's 12-speed systems, it is compatible with 1x11 setups as well. The direct-mount interface allows you to pair it with various chainring options, provided the chainring is compatible with your specific chain width.

Hollowtech II is Shimano's proprietary forging process that creates hollow crank arms. This design significantly reduces weight without sacrificing stiffness, ensuring the cranks are robust enough for aggressive trail riding while maintaining efficient power transfer.

The M9120 is primarily built for trail and enduro riding, offering a balance of strength and weight. If you are looking for the absolute lightest option for pure cross-country racing, you might consider the M9100 series, but the M9120 is an excellent choice if you prioritize durability and stiffness for more demanding terrain.
