Hi all, I recently acquired a 1993 bridgestone xo-1 in bad shape & will be attempting to restore it. I'm sending it to velocoluor for a repaint & have asked them to spread the rear triangle to 135mm. the original spread is 128mm, I guess to accommodate 126 & 130 rear wheels. I'm now wondering if this is a good idea, my original thought was to put mtb wheels on it. will this affect the chainline? I'm also looking for advice on a new bottom bracket/crankset combination any ideas? thanks
