Shimano XTR Enduro FC-M9120-1 Hollowtech II Crank

Shimano XTR Enduro crank FC-M9120-1 - with user-friendly direct mount system

The XTR Enduro FC-M9120 is one of the first Shimano cranks with Direct-Mount. More stiffness, less weight and increased user-friendliness are the main advantages of this system. The 12-speed compatible crank has a Q-factor of 168 mm. As FC-M9120-1 it can be equipped with only one chainring (not included), which saves even more weight, which benefits the performance in enduro races. However, it is quite possible to install two chainrings, which would then result in the FC-M9120-B2, which would be also available separately as a complete crankset. The version with only one chainring can be used in frames with 142 mm and 148 mm installation width thanks to a 52 mm chainline. FC-M9120 of course features Hollowtech II construction, which has been tried and tested for years and which creates an optimum balance between the strength of the crank arms, the stiffness of the axle and the weight.

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.
