The XTR PD-M9100 is a premium cross-country pedal. The SPD clipless design has remained practically unchanged since its release almost 20 years ago, but the XTR version receives the upgrades we expect from Shimanos top-tier products. These pedals have higher quality bearings for even smoother, more reliable performance. Precision machining creates more shoe contact, shaves off grams, and improves mud-shedding. No effort is spared to make Shimanos time-tested SPD design perform to the highest standard.
