The XTR XC FC-M9100-1 cranks by Shimano - stiff design, much flexibility
With the XTR XC FC-M9100 crank, Shimano introduces the direct mount principle, which means an increase in stiffness, user-friendliness and less weight. The 12-speed compatible crank has a slightly narrower Q-factor of 162 mm, suitable for racing. As FC-M9100-1 it can be equipped with only one chainring (not included in delivery), which saves even more weight, which benefits the performance in Cross Country use. However, two chainrings can also be installed, resulting in the FC-M9100-2, which is also sold separately as a complete crankset. The version with only one chainring can be ridden in 142 mm and 148 mm over locknut dimension frames thanks to 52 mm chainline. FC-M9100 naturally features the Hollowtech II design, which has been tried and tested for many years and provides an optimum ratio between the strength of the crankarms, the stiffness of the axle and the weight.

Note: This crank is not compatible with M9000 components and other 11-speed groupsets.
What matters is the overall balance of the crankset. With regard to the entire crankset, an optimum ratio between the strength of the crank arms, the stiffness of the axle, the bearing position and other features is very important. During the development of the crankset, the overall balance of all individual elements was carefully considered in order to ensure maximum stability.
Outer bearing: On most 68 mm bottom bracket housings, the Hollowtech II 24 mm axle can be mounted outside the frame for better weight distribution and stability.
High-quality precision seals: The Hollowtech II set also features high quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency over time.
The axle and the 24 mm diameter bearings ensure optimum balance of the crankset and optimum transmission of power to the bicycle.
