Why We Like The XTR FC-M9125 Crank Arms
As the premium option in Shimano’s lineup, the XTR M9125 Cranks are light, stiff, and ready for race day. This particular version uses a 55mm chainline and 174mm Q factor, which is ideal for 12 x 148mm Boost bikes that just need a bit more chainstay clearance than the standard 52mm chainline.
