A combined fore and aft cleat-adjustment range of 22 mm (11 mm from the outsole and 11 mm from the cleat) offers each rider the opportunity to find their best cleat position.
Power transfer efficiency
SPD-SL is the road specific refinement of the system. This pedal platform was designed specifically for the needs of world-class road racers. The seamless pedal and cleat interface for a more efficient power transfer under the extreme pedaling loads encountered in race competitions.
A wide cleat-adjustment range is enhanced by additional aft adjustment to deliver rider confidence for increased bike control.
22 MM OF TOTAL CLEAT-ADJUSTMENT
22 mm of combined cleat-adjustment range offers each rider the ability to select the best possible cleat position.
WIDER CLEAT ADJUSTMENT
Expands range for mounting cleats
The toe-spring section of a cycling shoe plays a key role in supporting efficient pedaling. Too high, and it causes increased tension in the plantar, calf, and hamstring muscles. Too low, and you get a bowlegged, inefficient pedaling form. Extensive research by Shimano's R&D experts has produced a superior shoe last design with an optimized toe-spring section that promotes a smoother, more energy-efficient upstroke. Built based on feedback from pro riders, Shimano Dynalast helps reduce energy loss on long rides, letting you keep more in the tank for that final sprint to the line.
S-PHYRE RC9 SHOE FOOTWEAR SUPERIORITY
The first-generation S-PHYRE RC9 shoe established a new benchmark for cycling shoe performance, weight, efficiency, stiffness, and comfort. Yet S-PHYRE is about always seeking improvement — always innovating to be better. The second-generation S-PHYRE RC9 is even lighter with enhanced hydrophobic materials to limit moisture retention, and features an improved heel cup and a revised pattern for improved fit and better transfer of power to the pedal. With S-PHYRE innovation truly has no finish line.
