Shimano SM-SH91 SPD-R cleats are designed for use with Shimano SPD-R racing pedals. They offer a wide range of adjustability to ensure a comfortable and efficient pedaling experience.

With 15 mm of front-to-back and 5 mm of left-to-right adjustment, you can customize the cleat position to suit your individual riding style and biomechanics. This adjustability allows you to optimize power transfer and reduce the risk of knee pain or other injuries.

The SM-SH91 cleats are also self-aligning, which makes it easy to clip in and out of the pedals. This feature is especially beneficial for new riders or those who are not yet comfortable with the SPD-R system.
