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?
I've built many "road" wheels with 135mm wide "MTB" hubs. No issues whatsoever. In fact, it's quite easy to replace the axle in a 130mm width road hub with a longer axle and add a 5mm spacer. I have a rear wheel with a Shimano 105 hub and Mavic A719 700C rim, and it's been perfect since the day I built it.
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.
Comcast nuked my web page. It will return soon..
