Shimano XTR Enduro FC-M9130-1 Hollowtech II Crank

The Shimano XTR Enduro FC-M9130-1 Crank - Specially designed for Super Boost

The Shimano XTR FC-M9130-1 crank for enduro and downhill is specially designed for frames with 157 mm over locknut dimension, but is also compatible with 148 mm. It produces a chainline of 56.5 mm and has a slightly larger Q-factor compared to FC-M9120-1, which at 171 mm is narrower than that of FC-M9125. The proven Hollowtech II construction provides an ideal ratio of stiffness and weight, especially since no expense or effort is spared in the high-end XTR series to save as much ballast as possible. The FC-M9130, for example, weighs 560 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. In combination with a Shimano Dynamic Chain Engagement+ chainring with a high-precision tooth profile (not included), you get a front drive of maximum 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.
