Shimano RX9 Wide SH-RX910 S-PHYRE

Shimano RX9 SH-RX910 S-PHYRE Wide is a top-tier gravel and adventure cycling shoe designed for riders who want near-road-shoe efficiency with the durability and walkability required for mixed-terrain riding. Positioned at the performance end of Shimano’s gravel lineup, it targets long gravel races, fast adventure riding, and endurance events where power transfer, stability, and comfort all matter.

The RX9 uses a high-stiffness carbon fiber sole tuned for efficient pedaling while incorporating a full rubber outsole with aggressive tread for confident traction off the bike. This makes it well suited for hike-a-bike sections, loose gravel starts, and technical terrain where traditional road shoes fall short. The wide fit last provides additional forefoot volume without compromising heel retention or pedaling stability, making it ideal for riders who find standard race shoes too narrow.

The upper features Shimano’s surround-wrapping construction paired with a dual BOA® Li2 dial system for precise, even pressure distribution across the foot. Strategic reinforcement improves lateral stability during hard efforts, while breathable materials help manage heat and moisture over long gravel rides. The RX9 is compatible with 2-bolt SPD cleats, reflecting its off-road focus and versatility.
