Tested over the past few months in the pro peloton, Shimano’s new Dura-Ace PD-7900 SPD-SL pedal replaces the aluminum body with a proprietary long-fiber injection molded carbon fiber to drop about 30g per pair.

The axles and bearings are contained within a billet aluminum cylinder bonded to the interior of the pedal body. This keeps the bearings from sitting directly on the carbon and provides a stronger, more durable design. Each pedal uses three sets of bearings to keep things rolling smooth and steady under load.

The top uses a redesigned stainless steel plate to create a durable but smooth contact patch for the base of the cleat, allowing it to move naturally without wearing into the carbon body.
