SHIMANO has lifted the curtains on its latest RX910 S-PHYRE Gravel Race shoe, offering gravelers and bikepackers alike “road-level power transfer, off-road capability, and all-day comfort.”
“Gravel racing is inherently contradictory. Riders need road-level power transfer for long stretches of pedaling efficiency, but also require some off-road traction for mud sections, river crossings, and technical terrain. SHIMANO’s new S-PHYRE RX910 gravel shoes resolve this contradiction, offering unmatched power transfer, walking stability, and all-day pedaling comfort in one streamlined package,” says the storied Japanese brand.
“Sure, you can get away with road or MTB shoes for gravel racing,” adds Pete Stetina, SHIMANO pro gravel racer who assisted in the development of the RX910 shoes.
“But to optimize for gravel performance, we need a light and stiff shoe that has a solid contact patch for steady power transfer plus the capability to handle the occasional hike-a-bike or muddy race.”
At the heart of SHIMANO’S RX910 innovation is the new Pontoon Cleat System. This new feature includes a pair of modular, replaceable TPU contact blocks that dramatically improve the shoe-to-pedal contact point and optimize power transfer. The system enables a road-shoe-like pedaling interface while maintaining SPD compatibility and off-road functionality.
“For me [the Pontoon Cleat System] is the most exciting point of this shoe,” says Stetina. “You now have road stability and power transfer while still having some off-road benefits of mud shedding and quick engagement of SPD.”
Unlike traditional outsole-mounted contact blocks, the RX910’s pontoons are part of the cleat interface itself. This means they move with your cleat position – vertically or laterally – for consistent support and efficiency, no matter how your cleats are set up. Plus, the pontoons are replaceable, allowing riders to start every race with a solid shoe-pedal interface.
The RX910 is ideally paired with SHIMANO SPD pedals. Best matches include the PD- M9200 and PD-M8100 for seamless power delivery and dual-sided entry, which is a must for high-stakes remounts and technical terrain.
While the RX910 is engineered for elite gravel racing, it’s an excellent choice for performance-minded riders seeking a shoe that offers road efficiency and off-bike comfort. “Whether you’re racing to beat the sun in Kansas, taking the lesser-known route to your local coffee shop, or exploring off-road, the RX910 is a compelling option for both performance and comfort,” boasts SHIMANO.
The RX910 sells for $480.00, which is available through SHIMANO retailers and distributors worldwide, as well as online at Ride.Shimano.co
