The best of road and mountain bike shoes, that's the Pontoon system of the Shimano RX910 S-PHYRE for gravel

Shimano has just launched their new RX910 S-PHYRE shoes, a model designed from scratch specifically for gravel and developed in collaboration with professional gravel cyclists. It combines the stiffness and efficiency of a road shoe with the traction and comfort needed to meet the demands of competitive gravel riding.

New Shimano RX910 S-PHYRE: performance inspired by gravel professionals

Competitive gravel riding is becoming more specific and it is undeniable that it has different needs compared to other disciplines. One of the most notable is the need for maximum power transfer on long straights, but also all-terrain capability to tackle mud, river crossings, and technical trails. Shimano has solved this dilemma with the RX910, which offers all-day comfort, stability when walking, and unprecedented pedaling efficiency.

Pete Stetina, a professional road cyclist who now competes in gravel, actively participated in the development of the model and summarizes it as follows:

“To optimize performance in gravel, we need a lightweight and stiff shoe, with a solid contact surface to maintain power transfer, but also capable of tackling muddy or walking sections. That's exactly what the RX910 offers.”

Revolutionary Pontoon cleat system

But the big innovation of this release is the Pontoon cleat system, a pair of modular and replaceable TPU blocks that are an active part of the interface between cleat and pedal. This system offers stability similar to a road shoe without losing compatibility with SPD pedals or all-terrain capability.

Unlike traditional sole supports, the pontoons move with the cleat, always maintaining optimal support in any configuration. In addition, their replaceable nature ensures solid contact race after race.

For those seeking the best synergy, Shimano recommends combining the RX910 with SPD PD-M9200 or PD-M8100 pedals, which offer entry from both sides and smooth power transmission.

The brand clarifies that the RX910 is not a compromise between road and mountain, it is a specific solution for gravel. Its design integrates the most recognized advances of the S-PHYRE range, from the stiffness of the carbon sole to the micro-adjustable BOA® fit.
