spd sl cleats and pedals Shimano SPD-SL Cleats – 1 2 CYCLE

What is Cleat Float?

The key differentiator between the three Shimano cleat options is the amount of float each allows. Float refers to the back-and-forth movement of the foot while you are clipped in and is essentially how much you can point your toes left or right while your shoe is attached to your pedal. Different levels of float help accommodate different riding styles or help with biomechanical issues such as lack-of-flexibility, past injuries, or knee pain. While float can help reduce stress on joints and make for a more comfortable pedaling movement, it can also result in a feeling of slightly less power transfer if your foot moves around too much.

Your neutral foot position is also important to understand before selecting and installing the right SPD-SL Cleat for you. The neutral position of the foot is defined as its most natural or efficient angle while pedaling. For some athletes, this means that both feet point perfectly straight forward. For others, the toes naturally point slightly inward or outward. If you’ve had an injury on one side of the body, your neutral position may differ between your left and right feet.

Yellow SPD-SL Cleats – 6 Degrees of Float

Yellow SPD-SL cleats are perhaps the most popular among casual fitness cyclists but are used by a wide range of athletes. They're characterized by a six-degree float range (three degrees in each direction), which allows for free movement and low joint stress. The float’s pivot point is in the center of the cleat, allowing the toes to point in a wide range of angles. This large float range also provides more room for error when setting up your cleats. If you're new to cycling, experience knee pain, lack flexibility, or simply don’t know where to start, Shimano’s yellow cleats are your best bet.

Red SPD-SL Cleats – 0 Degrees of Float

Red SPD-SL cleats have no float and are 100% fixed in position. This makes them great for sprinters, professional athletes, or people who value the most efficient power transfer possible and are not prone to knee pain. Note that red SPD-SL cleats require that you know your optimal cleat position precisely, and you are comfortable adjusting your cleats into that perfect position.

Blue SPD-SL Cleats – 2 Degrees of Float

Blue SPD-SL cleats are Shimano’s newest cleat option and they exist as a middle-ground between yellow and red. Blue cleats have two degrees of float (one degree in each direction), allowing for a small range of movement while still delivering a high amount of pedaling efficiency. The float pivot point is at the front of the cleat, which eliminates lateral sliding movement while allowing a small amount of angle change from the pivot point back towards the heel.
