Pedal Taps

The reviewer discusses using pedal taps to repair damaged threads in bicycle cranks. He demonstrates using a left-hand tap for the left crank and a right-hand tap for the right crank, noting that using a right-hand tap from the back does not work. The taps were purchased from AliExpress and are not expensive. He successfully cleans the threads, and in one case, only the first thread was damaged, so an insert was not needed. He also cleans up the pedal threads with a wire wheel and applies grease before reinstalling.
