Supreme-C pedals feature a low-profile design using super tough reinforced nylon designed to offer the optimum balance of light weight and reliable performance in all kinds of weather conditions. The low-profile design with a deep concave shape allows your foot to "sit-in" the pedal and improves grip/comfort. It uses premium dual-sealed bearings/DU bushings to keep the elements out and to provide smoother and more durable rotation. It features an over-sized 12mm spindle to increase stiffness and strength. It comes with 18 replaceable steel pins that offer grip in the most challenging of situations.Nylon reinforced composite body with concave shape for secure feelCNC machined chromoly 12mm oversized spindleDual sealed bearings + one DU bushingIncludes 18 replaceable stell grip pins for maximum grip
