Since its release in 1985 the RX-1 has been a favorite on the Japanese professional track racing circuit. Our finest bearing systems offers the highest level of rotational performance available on the market, and each pedal is built by our most experienced employees who assemble and adjust the RX-1 one at time. The RX-1 is our lightest Track racing pedal. As it was designed and built for professional track racing, the NJS certification is stamped onto every pedal using the NJS mark. The RX-1 uses the same bearing system as the SUPREME, but since it s built around a solid axle the RX-1 has a stiffer ride quality that is ideal for the velodrome. We highly recommend you use toe clips and or straps with the RX-1.
