Shimano makes entry level and performance-oriented pedals for road, gravel and mountain bike riding. Shimano road pedals use an SPD-SL (3-bolt) cleat while the mountain bike and gravel pedals use a SPD cleat (2-bolt). These pedals are available in a variety of materials including aluminum and carbon. In addition, the mountain bike pedals are available with or without a platform to provide you with either extra contact points or reduced weight.
