The Shimano PD-7900 Dura-Ace SPD-SL feature long fiber injection molded carbon body (injection molding insures precise shape and consistent material distribution and creates a stronger body); three separate sets of bearings along the axle create better pedal stability and smooth rotation regardless of load. An independent billet aluminum cartridge creates a more durable bearing interface and preserves both carbon body and bearings. Easy cleat tension adjustment at pedal back plate and a new design stainless top plate protects the carbon body from wear. The Shimano PD-7900 Dura-Ace SPD-SL pedals weigh 248-grams (pair) and retail for $250. For more information visit: bike.shimano.com
