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.
4mm Longer Axle- Shimano’s optional extended axle adds 4mm to the distance between the crank and the foot position. This allows riders with naturally wider hips to maintain correct leg and foot alignment on the pedals.
