At the forefront of Shimano's 12-speed mountain groups is XTR, which is the most lightweight version they can manufacture. The Shimano XTR FC-M9130 Crank Arms are a key element in this system, contributing to the group's strength and overall weight.
The Shimano XTR FC-M9130 crank arms feature an entirely new construction and a narrow 171 mm Q-factor. The FC-M9130-1 also uses a 56.5 mm chain line and can be converted between 1x and 2x.
FEATURES:
Rigid and lightweight design for trail riding with direct mount chainring
