Re: Please help me with sourcing wheel bolts?!
ok have made some progress, I think.
Found a copy of the official paperwork for the Borbet Xbs, there was a copy still in one of the boxes.
This states that the bolts should be M14 x 1.5 SPHERICAL wheel bolts, sphere diameter 25.6mm - I am assuming that is a clear indication of radius rather than taper!
