Designed in collaboration with professional athletes like Pete Stetina, this system redefines the standards of gravel riding by combining power transfer worthy of the best gravel shoes route, all-terrain stability and optimal comfort for long distances.

The Pontoon system: an innovation at the heart of performance

The true g of the S-PHYRE RX910 resides in the Pontoon bilge system, an exclusive innovation developed by Shimano to meet the unique demands of gravelUnlike traditional cleat systems, the Pontoon incorporates replaceable modular TPU contact blocks that optimize the interface between the shoe and the pedal. This design significantly improves power transfer while maintaining compatibility with SPD pedals, essential for technical and muddy sections.

« The Pontoon system is what makes this shoe exceptional " explains Pete Stetina, a professional gravel cyclist involved in the development of the RX910. " It offers the stability and efficiency of a shoe route, while maintaining mud evacuation and the quick engagement of SPD pedals, essential for gravel. »

Pontoon blocks are distinguished by their direct integration into the bilge interface, allowing a personalized adjustment (vertical or lateral) for constant stability, regardless of the position of the cleat. In addition, their replaceable nature guarantees a shoe-pedal interface that is always optimal, even after demanding races.

Paired with Shimano SPD pedals like the PD-M9200 or PD-M8100, the Pontoon system ensures reliable engagement and smooth power transfer, even in the most technical conditions.
