Hi.
Was tightening one of the bolts in my brake mount and about half way in there was a noise and the bolt went loose and would not tighten, just spin.
I'm guessing its going to need helicoiling.
Will a local bike shop be able to do it. If not anywhere else that possibley local.?
and If i have to do it, what size are the standard threads and what does it need changing to?
Thanks
