Derailer thread question
 

i just found a really nice Trek frame. The derailer hanger is striped. I want to buy a rethread kit. The hangers are all a standard size but I dont know what the size is. Does anybody know off hand?

Actually they are not all standard sized.
Campagnolo is 10 x 26 tpi
"Everyone else" is 10 x 1 (25.4)
for the few turns of a hanger, it works.
if you need a Helicoil, then 10 x 1 will work, but you will have to snip off the excess most likely.
