Get a torx or something similar, hammer it in & try to undo  :daumenhoch:

Or if no good drill it & try an easy out  ???

its the one that holds it on the forks .tightened and loosened the other one to see if it made any difference but didnt then the allen key moved and killed the shape of the allen part of the bolt .

whats a torx and easy out ?????

cant you try and whack a slightly bigger allen key in
as ive done that b4
easy out is a reverse drill bit
as it drills in it winds the bolt out

Greg is it an 1 1/8th new school stem we are talking about here. If its a standard or an s+m you need an imperial allen key. :)

Greg you deffo need an imperial allen key < if you use the right one you may still be able to undo it without to much bother 7/32th is the size I think but will check my tool box to be sure.  :daumenhoch:

Imperial for sure.

Tighten the other bolt as much as possible.  Hammer in a torx fitting to the problem bolt as others have suggested and with a bit of luck you'll be able to wind it out.  The important bit is that the good bolt is as tight as fook.  ;)
