Shimano XTR Enduro Crank FC-M9120-B2 Hollowtech II w/ TL-FC41 Tool

The XTR Enduro FC-M9120-B2 Crankset by Shimano - Ideal for unknown terrain

The Shimano XTR Enduro FC-M9120-B2 is a crankset for enduro use and comes with a TL-FC41 chainring tool. It has a chainline that is 3 mm further out, as is the case with bikes with 148 mm rear over locknut dimension. The crank comes with two chainrings, whereby the large chainring is installed according to the Direct Mount principle. FC-M9120-B2 has a Q-factor of 168 mm and is only intended for use with 12-speed drivetrains. The model is aimed at riders who require flexibility and the widest possible range in unfamiliar terrain with potentially steep climbs. Of course, the aluminium crank also features Hollowtech II construction, which has been tried and tested for years, creating an optimal 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.
