The Shimano SH-RX9 SPD Cleat Pontoons redefine gravel racing efficiency by delivering the stability of a road shoe with the versatility of off-road performance. Designed specifically for the S-PHYRE SH-RX910 gravel shoes, the pontoon system increases the contact area between pedal and shoe, ensuring maximum power transfer and efficiency across long distances. Unlike standard SPD setups, the pontoons provide consistent, stable engagement in any cleat position, minimizing energy loss during high-paced efforts. Their easily replaceable design allows riders to swap in fresh pontoons before a race, maintaining steady contact without needing new shoes. Compatible with all SPD pedals—though optimized for peak performance with Shimano XTR PD-M9200 and DEORE XT PD-M8100 models—the SH-RX9 pontoons combine adjustability, stability, and durability for serious gravel racers. Sold as a pair, they deliver the seamless pedaling efficiency and off-bike confidence needed to conquer unpredictable terrain, stream crossings, and rocky hike-a-bike sections with ease.
