Comfort to the WalkSHIMANO invented SPD to meet the needs of a growing frontier lifestyle called MTB. By eliminating toe-clips and integrating the pedal and outsole into a single, unified power transfer system, SHIMANO changed the industry; not only boosting power to the pedal, but also the rider's control over increasingly adventurous styles of riding. Today there's no single MTB style, and no single SPD pedal to match. It's all over the landscape, from fast paced XC racing to steep, rocky, wet, rooted and muddy trails. SHIMANO SPD pedals are keeping up. The legacy of "in-the-dirt" dependability, reliability and sheer endurance continues as shoe-pedal designs evolve to meet the needs of your personal style of ride. System-engineered. Rider-tuned. You choose.SPD is a system that performs whether you're on or off the bike. It makes pedaling more efficient with a wide variety of shoe and pedal styles and the recess cleat makes walking more comfortable. You can pedal with greater efficiency, stability and comfort with the SPD system.
