In the world of cycling, there are only three possible threads for pedals:
- The 9/16" (14.29 mm x 1.27 mm) : This "English-pitch" thread is today's must-have. It is the universal thread for all adult and children's bicycles, pedals and cranksets of any brand.
- The 14 mm x 1.25 mm : The historic and typical threading of old French bikes but which is no longer used today.
- The 1/2" (12.7 mm x 1.27 mm) : This type of thread is not very widespread. We find it on one-piece cranksets on old bikes or children's bikes.

In any case, for these three types of threads, so as not to loosen while driving, the right pedal has a standard thread (from left to right) and the left pedal has a reversed thread (from right To the left).
