New wheelset, spacing question
 

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.

really?

can i assume you'll be putting a longer axle and spacers in the rear hub to extend it to 130? i don't know enough about wheel building to say for sure, but i suspect you will have a dishing problem as well.

just torquing a 130mm frame down to 120 doesn't strike me as a very good idea, but then there's a lot of things here on SSFG that don't make sense to me...

the rear spacing on my frame was 6mm wider than my 120mm hub. I used a frame alignment gauge when bending the rear so I know I have perfect alignment and 6mm isn't that much. 10mm seems like alot to squeeze and you may run into issues with your rear dropouts if they're not perfectly parallel.

If you do decide to use a longer axle and spacers you might be ok with chainline on both fixed and free if you have the same distance in spacers on both sides of the wheel but who knows if you'll be lined up with your chainring. You might have to try bolting the chainring on the inside or outside of the cranks or maybe even get a new bottom bracket.

As far as the front hub spacing - just contact your wheel builder and find out what size front they're using. I dont' remember if my front hub spacing was 96mm or 100mm.

Thanks. And yeah, I didn't mean bending the frame, I'll be using spacers.

Numbering to try to cover all of your questions...
1. Formula rear hubs have a long enough stock axle to space to 130mm.
2. The only difference between the 120mm formula and the 130mm is that the latter already has the spacers installed.
3. If you space the axle equally on both sides, the chainline for both sides of the hub will be right around 42mm (depending upon what cog & freewheel you use). Compare that to the distance between your chainring and the center line of the frame.
4. Front hubs are 100mm, virtually without exception.

That answers pretty much all of my questions! Thank you!
