Warning: a stripped pedal thread on a rental bike in Moab taught me a hard lesson
I was working at a shop in Moab last season when a customer rolled in with a rental bike that had a crank arm pedal thread totally stripped out. The rider had tried to swap pedals themselves and cross-threaded it badly. The shop I was at had a policy of just replacing the whole crank arm, which meant a $75 part plus labor for a simple mistake. It felt wasteful and expensive for the customer. That day, I went home and ordered a helicoil kit for M14x1.25 threads, the standard pedal size. Now, for simple aluminum crank arms, I tap and insert a helicoil. It takes about 20 minutes and costs maybe $10 in parts, saving the crank from the scrap pile. Has anyone else found a good, reliable fix for this besides a full replacement, or do you think it's not worth the risk?
