I lost one of the rear caliper mounting bolt. Does anyone know the bolt size? I know is a M10, Is the pitch 1.25 or 1.3? I measured 1.3 but it seems 1.25 is more popular on the web.

I like to get a replacement bolt but it seems 1.3 is very unpopular. It is hard to find on the web.

Can anyone confirm it is a
M10 -1.25 *30 or a
M10 - 1.3 * 30 ?


Any help is appreciated.

 

Take same one out of other side and go to your local nut and bolt man and ask him for one the same.
