I have clipless pedals that I love and my standard flat pedals with toe clips. However, the clipless pedals just aren't comfortable for me to wear without cleated/clipless shoes, and they tear up my regular shoes. I don't want to bring extra shoes with me every day to work, so every weekend I've been changing out my pedals for clipless and on Sunday evenings changing them back to flat for the week's commuting. I don't mind spending 15 minutes a week doing this, but will this lead to long-term problems, like the crankshaft/pedal getting stripped or getting stuck?
Changing pedals every week should not cause problems long term if correctly done.
Here are the possible types of issues changing pedals could create.
- Cross threading - this includes normal cross threading and getting the wrong pedal on the wrong side.
- Thread wear - from installing and uninstalling - cranks are aluminum (usually) and pedals are steel (usually). Wear would be on the softer material - usually aluminum.
- Over / under tightening - over tightening damages threads in the softer material, under tightening risks the pedal working it's way out tearing out the last few threads in a worst case scenario.
All that being said correctly uninstalling and installing pedals should not cause long term problems.
