Shimano S-Phyre SH-RC902 Road Shoe
Function-specific zones maximize power transfer
Utilizing its Bikefitting.com pedal analyzer, Shimano engineers took a 3D look at pedaling dynamics to better understand how pressure is applied throughout the pedal stroke. The engineers discovered distinct zones where force is exerted differently across the shoe and optimized the new RC902 shape and materials to maximize power transfer while maintaining a comfortable and lightweight design.
The Shimano S-Phyre SH-RC902 Road Shoe has an upper construction features ultra-breathable, reinforced mesh and micro-fiber leather materials that are layered in different regions to maximize fit, flexibility, rigidity, and ventilation. The RC902's upper construction is more rigid toward the rear of the shoe to hold the foot securely in place while more flexible and elastic materials are used up front to increase comfort.
Optimized power transfer for the hardest efforts
Also utilizing findings from the Bikeftting.com pedal analyzer and exploring additional movement studies, Shimano redesigned the RC902 heel cup to optimize fit and foot stability. With Shimano’s new anti-twist stabilizer heel cup technology, the RC902 is built to handle intense twisting forces caused by the most explosive accelerations. It features a mix of rigid and flexible materials that stabilize the top section of the heel cup to reduce foot movement and increase power transfer.
The only aspect of the new S-PHYRE shoe that remains unchanged is Shimano’s rigid and responsive level-12 carbon sole. Built to maximize power transfer and speed, Shimano's S-PHYRE shoe lineup has been part of countless victories in the world's highest level races since first introduced in 2017. Now, for 2021, the new Shimano S-PHYRE experience is even faster.
