Shimano XTR FC-M9130 Crank Arms

Description

The Strongest, Lightest MTB Cranks Shimano Can Make

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, direct mount chainrings, a special gear tooth profile for improved chain retention, 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. The Shimano XTR FC-M9130 Crankarms come in 165, 170, and 175 mm lengths.
