MTB 135mm hubs on a road bike?
what kind of problems (other then needing to cold set my frame) will I run into if I use a mtb 135mm hub?
current bike is 126mm... so logic tells me the chain line would move out about 5mm... in reality will this give me any real issues? should I just stick with some 130mm hubs?

Out fishing with Annie on his lap, a cigar in one hand and a ginger ale in the other, watching the sunset.

It needs to be a steel frame to be spread, Aluminum isn't smart to do this with. One immediate concern.

As others said, cold-setting (aka "bending") the frame for the wider hub is allowable if it's steel, chancy if it's aluminum, and impossible if it's carbon-fiber.

lol a point you'd think would be obvious... 
but yes... we're dealing with an early 90's 126mm lugged steel frame
I think my biggest concern is the chain line... which could be fixed with a wider BB... but that increases the Q...
any other problems that i'd get to deal with?... other then limiting myself to a steel frame or MTB for future options

Is it a geared bike or single speed? If it is geared it shouldn't matter. I switch between a 130 and 135mm hub on my Cross Check without adjusting the derailers at all.
