Pedal weight becomes a talking point when you're already running a Dura-Ace drivetrain and the easy grams are gone. The PD-R9100 addresses that conversation with a 228-gram pair weight, achieved through carbon body construction and stainless steel body plates that resist cleat wear without adding unnecessary mass. This is Shimano's lightest SPD-SL pedal, sitting at the top of their road pedal hierarchy.

The platform measures 65mm wide, which distributes pedaling force across a broader section of your shoe sole than narrower designs. Three sealed cartridge bearings per pedal handle the axle rotation, a configuration that prioritizes long-term durability over the single-bearing setups found in weight-focused competitors. Stack height measures 7.1mm from axle center to shoe interface, the lowest in Shimano's SPD-SL range, which keeps your foot closer to the pedal spindle.
