Fixed-Position SPD-SLR Cleats for Maximum Pedaling Efficiency The SHIMANO CL-SL100 is a fixed-position SPD-SLR road cleat for riders seeking a locked-in connection and maximum pedaling efficiency. Its zero-float design pairs with the lower-stack SPD-SLR system for a direct, stable connection between shoe and pedal. Features Fixed Position: SHIMANO Red CL-SL100 SPD-SLR cleats have no float and are 100% fixed in position, making them ideal for sprinters, professional athletes, or any rider seeking maximum efficiency and power transfer above all else Stable Connection: The SPD-SLR-specific design creates a seamless pedal connection for enhanced stability Precision Cleat Setup: Multiple alignment markers make cleat adjustments easier, while a center window provides a clear view of the outsole grid found on Shimano shoes for accurate positioning Lower Stack Height: A lower stack height than previous SHIMANO road cleat and pedal models for a more direct shoe-to-pedal connection Improved Walkability: A thinner rear section of the cleat improves off-bike walkability System Engineering: Lateral cleat adjustment works with fore-aft adjustment built into the newest Shimano road shoes Pedal Compatibility: Compatible with Shimano SPD-SLR pedals: not compatible with SPD-SL pedals New Cleat Adjustment With the newest SHIMANO road shoes, fore-aft positioning is handled at the shoe while the SPD-SLR cleat provides lateral adjustment. Dividing adjustments between shoe and cleat supports precise positioning while allowing the cleat itself to use a more compact, lower-profile design. More Direct Connection The SPD-SLR cleat and pedal interface lowers stack height by 2.3 mm compared to previous Shimano models for more direct power transfer and greater pedaling efficiency. The integrated design creates a seamless connection for a more stable, connected feel.
