Built for riders who race gravel, the Shimano S-PHYRE RX910 turns long, demanding efforts into efficient forward motion. A full carbon sole delivers stiff, responsive power transfer, while the low-stack SPD design keeps the connection to the bike direct and efficient across mixed terrain. The pontoon cleat system adds a wider, more stable platform for control on rough sections, and the dual BOA closure provides a secure, precise fit that holds steady through climbs and accelerations. Lightweight and race-focused, the RX910 keeps you locked in, stable, and efficient from start to finish.
