How often do you need to replace your Shimano cleats
Cleat replacement depends on how often you ride and the conditions of the terrain. “Race mileage” riders may need to change their cleats as often as one or two times a year to keep the specifications.
A good rule of thumb is that cleats should be replaced when there is a change in the release/engagement effort. If the cleat begins to “float” more and releases at a greater angle, inspect the cleat for wear. Eventually, the vertical tab on the cleat that opens the retention mechanism becomes worn and greater effort will be required to disengage.
We are often asked which cleat is the best. It all comes down to your knee and riding style.
Generally we only recommend red “no float” cleats for track riders who need a firm and precise footing on the pedal. This is crucial under these extreme conditions but only after a proper bike fit.
No float clips can seriously damage your knees if your bike is incorrectly setup.
