So I got around to taking a few more pictures of the frame. There's two photos of the brake bridge, I can't really see much separation and there is some sort of bolt holding it on as well.




In this shot there might be a bit of separation, but I'm not sure if that will affect the ride or frame integrity enough to worry about it.




This is what's actually causing me problems though, because of the extra width, the cogs are pushed so far out that even in the gear combination shown, the chain line is very angled.




I think what I've decided to do is just get a new wheelset built on some sort of 135 mm touring or mtb hub. Probably wrong forum, but does anyone have any tips or know what ones are good?
