Race day is all about maximum output and maximum efficiencyputting everything you've trained for into the race, and leaving it all out on the racecourse. The new XTR Race pedals connect riders to their bike like never before, maximizing the renowned strength and stiffness of XTR cranks with complementary XTR Race pedals, which use wider bearing placement for ultimate rigidity under load. These new pedals boast four times the shoepedal contact area as the previous generation XTR pedal, helping channel every ounce of effort to the rear wheel. This refined design retains all the time tested and race proven functionality SPD is famous for, and adds a slimmer axle profile to reduces weight and increase mud shedding capability. This new pedal also provides a lower and more biomechanically correct platform height, which more efficiently transfers power into the drivetrain while picking up precious millimeters of ground clearance at the same time. Simply put: XTR Race SPD is the most efficient and controllable race day pedal Shimano has ever produced. The racers choice for generations, the original SPD pedal design has been highly evolved into its lightest and most efficient form. PD M980 reduces pedal height while increasing pedal to shoe contact.
