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.
