Thanks for all the replies, but the question that I was really interested it is would it be possible to take a 120mm hub, and respace it to 130mm, is all that is necessary for this a longer axle? 135 would not help at all, I'm working with a 130mm frame. I'd also like to avoid spending over $100 on just the rear hub, as some of the wheelsets I'm looking at are only $150ish.
