SPD-SL is a road pedal platform systematically engineered with SHIMANO footwear to transfer more power from your body to your bike. For pro riders the extra-wide, low-profile cleat distributes energy more evenly over a wider surface and transfers it more efficiently to the bike, under the most extreme pedaling loads. No wasted movement. No loss to flex, voids or mismatched shoe/pedal designs. It’s a core advantage that helps win races. The same energy efficiency that powers pro riders to the podium enhances the experience of other rider categories. Increased endurance for longer rides. More comfort and fun! System-engineered. Rider-tuned. You choose.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.SHIMANO DYNALAST - Creating Pedaling Efficiency and Optimized Shoe Last - 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 Research and Development 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. Tension in plantar area affects leg muscles A wider range of motion supports a smoother, more efficient upstroke.CLEAT SETTING - 6 SET INITIAL CLEAT POSITION USING YOUR ARCH LENGTH - Set the initial cleat position according to the difference between shoe size and measured arch length. If the arch length is longer or shorter than the shoe size, the cleat maybe positioned fore or aft from the center line of the cleat range of the shoe by the difference of the scale. *For example, if the right shoe size is 43 and the arch length measurement is 44, the cleat should be positioned (distance A) forward, toward the toe end, from the cleat range center line of the shoe sole. UPPER-TECHNOLOGY - The construction of our uppers and closure systems are customized to the characteristics of each rider’s foot. Our Surround Wrapping Upper surrounds the whole foot with a seamless piece of leather, which creates a better fit with fewer gaps between shoes and feet.
