|I was wondering if anyone could help. I just picked up a new bike frame. A Cinelli proxima. I'm running into some incompatability issues. I'm in the process of building it up by swapping over some parts off of my old bike, a Cannondale equiped with ultegra. The BB didn't swap over but I wasn't suprised, looks like i'll be picking up a 70mm IT BB soon. The the other issue I ran into was a problem with my wheelset. The dropouts seem a little more narrow than usual. I've been training on this wheel i picked up at performance with a 'forte' hub. It doesn't seem like its going to slide into the drop outs too easily. Do I need to stick to only certain brands of wheels?

|All current road bike frames have 130mm spacing. An Italian road frame most certainly will. Perhaps a cross bike or hybrid might have 135mm dropout spacing to make use of MTB hubs.
It would be unusual to find a road hub that did not have 130mm spacing.
Why not measure the dropout spacing with a scale. A 6" machinist's scale works great, but even one marked in 1/32" increments will do. 130mm converts to 5.118 inches, which is very close to 5-1/8". If the spacing in 1-2mm less than 130mm, it's just normal frame building tolerance. Many frames are 1-2mm wider or narrower than 130mm in the "free" state. As long as the frame is aligned with the hub clamped in place, that's all that matters.
You could also measure the hub spacing on your wheel to be sure that an MTB hub was not used by mistake, but this will require some calipers to take an accurate measurement.
