Recently washed road bike now squeaks when pedaling or coasting
When does it squeak?
If it squeaks even while you are coasting it can’t be the bottom bracket, chain, pedals or rear derailleur. If it only squeaks while you are coasting it could be the free wheel.
If it squeaks all the time it could be the brakes (should be more of a rubbing sound) or hub bearings (though those usually don’t “squeak”).
