What is the thread size (or most likely thread size) for where the gear-changer at the back wheel is bolted to the frame?
My Son (aged 10) has attempted some kind of repair by unscrewing his, and trying to "twist" the bracket, because the gear-changer was almost touching the spokes, and now the bolt won't re-engage into the hole, so I'm going to try and "clear-up" the threads with a tap, but I need to know what thread size?
Many thanks.
