I've read that link and seen what people are saying. I found a fixed wheel built on a 120 rear hub that is able to be spaced to 126, so that problem is solved. And for the front, I have a wheel that is nice and straight with a long axle but it's pretty narrow. I think 3 mm spacers on each side of that one will take up the space. I'm going to take it to my LBS and have them take a look at it.
