A pedal needs one thing from a bike: the crank's pedal thread. Almost every adult crank is 9/16" × 20 tpi; one-piece and many kids' cranks are 1/2". When the spec sheet does not say, we do not guess.
- How do I know whether a part in this category fits my bike?
- Every part page lists the standards it requires and its computed verdict on each bike in the fleet, with its confidence and sources. An "unknown" verdict means we do not have the measurement on file — not that it fits.
