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.
