My wheels are too hammered to keep truing. The bike was a craigslist find, an old nakamura road frame, rather nice, at least to me (butted, 4130, short wheelbase, wicked blue colour).... Anyway.

I plan on buying the Mavic CPX 22 w/ formula hubs, they are 120mm. My rear spacing is 130mm and according the searching I've done around here it shouldn't be a problem. There was some stuff about chainline that I didn't really understand regarding the flip flop hub, is this going to be a problem when switching between the fixed/free?

And lastly, my front fork spacing is about 95mm or thereabouts (loose measurement with the wheel still in place). Is this standard? I have no idea what the standard is but I figure there isn't much variation if any because I never hear people mention it but I wanna cover my bases cause I want to open the box when it gets here, mount everything and not worry about it.
Thanks

edit: oh yeah, I want the 120mm hub for sure because by next year I think I'll be getting a new frame anyway. I figure I have more options with the smaller hub vs getting a 130mm hub.
