Shimano XTR Enduro FC-M9125-1 Hollowtech II Crank

The Shimano XTR Enduro FC-M9125-1 Crank - For 148 mm Over Locknut Dimension, Large Q-factor

The FC-M9125-1 Enduro crank from Shimano's XTR series is, in contrast to the FC-M9120, only compatible with frames with 148 mm over locknut dimension. It produces a chainline of 55 mm and has a significantly wider Q-factor of 174 mm. This supports manoeuvrability in aggressive trail riding. The tried-and-tested Hollowtech II construction ensures an ideal ratio of stiffness and weight, especially since everything is done to save as much ballast as possible in the high-end XTR series. For example, the FC-M9125 weighs approx. 570 grams and is thus clearly below the level of comparable XT or SLX cranks. The model is based on a direct-mount system that ensures a quick chainring change. Combine it with a Shimano Dynamic Chain Engagement+ chainring with a high-precision manufactured tooth profile (not included) and you get a front drive of highest efficiency and low noise that guarantees good chain retention.

Technology:

Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
