Shimano PD-T421 CLICK'R pedals for mountain and trekking bikes. On one side they have CLICKR' locks, while the other side is a platform without pins. Reflectors and SM-SH56 cleats are included. This is a new rider-oriented pedal system, starting with foot pedals. In comparison to common pedals or pedals with clips, they provide incomparably more energy transmission from the rider’s foot into the bike Pedals: The SHIMANO CLIC'R allows you to ride faster and longer with less fatigue.
