Shimano XTR M9125-1 Crankarms

No, these specific crankarms are optimized for 12x157mm Super Boost spacing. They will not provide the correct chainline for a standard 148mm Boost frame.

The 168mm Q-factor is relatively narrow, which helps keep your feet closer together while pedaling. This promotes a more natural, efficient pedaling stance that many riders find more comfortable and ergonomic for long days on the trail.

These crankarms are specifically engineered for 12-speed drivetrains. While they might physically fit, the chainring and interface are optimized for the precise tolerances of Shimano's 12-speed systems, so we recommend sticking to that setup for the best performance.

Hollowtech II construction uses a hollow-forged design to remove excess material without sacrificing structural integrity. This results in a crankset that is exceptionally stiff under power transfer while remaining light enough to keep your bike's overall weight down.

The direct-mount interface is designed for simplicity. It allows you to swap chainrings quickly using standard tools, making it easy to adjust your gearing for different terrain without needing to remove the entire crankset.
