Clipless Pedals (MTB)

Clipless pedals are extremely efficient, providing a secure connection with the bike and zero power loss when climbing or sprinting. Mountain bike clipless pedals are all double sided, and use metal shoe cleats for strength and durability, although the binding mechanisms can be subtly different.

To clip-in, you simply place the cleat on the pedal and press down. The best systems make this process instant and smooth, so that it quickly becomes instinctive. All the mechanisms have built-in float. This is basically a bit of wiggleroom between the cleat and binding, so you can use more body English when riding through technical sections without your foot unclipping accidentally.


Disengaging should happen in a smooth and predictable manner. Inconsistent release is a big worry, particularly for first timers, as toppling over can hurt — even if it’s just your pride.


Terminology

Platform


The small platform can give support, allow easier cleat location and act as a temporary base for those occasions when you havent quite clipped in.

Float


Pedal float refers to the amount of free movement of your foot before the mechanismn releases. There are two types of float, lateral (side to side) and angular (twisting).

Sealing

As with anything that spins on your bike, the peda needs goog seals to protect the bearings and bushings. Even with the best of selas, it is a good idea to pull the pedal apart now and force some grease through the body to repel water and dirt.

Release tension


On some clipless pedals, you can adjust the force needed to relase the cleat from the mechanism. If you are riding fast on hard or technical ground, increasing the tension can prevent unwanted releases, but you might prefer it set lower if you are new to clipless pedals or are breaking in a fresh set of cleats.

Cleats


To allow your shoes to clip into mechanism, a pair of metal plates is included with every pedal. These attach to the bottom of the sole via two bolt interface. Cleats are pedal specific, so one system will not work with another. They also wear out so its worth replacing them every 12-18 month.
