Dropout Spacing Question (or What have I gotten myself into...)

I just bought a Nishiki Prestige frameset, and belatedly realized the dropout is 126mm. I realize that the frame can easily be spread (esp. since it's only a 4mm difference), but will this raise an issue with the brake calipers? And will there be a chain clearance issue due to the bigger cassette?

If there are no real concerns, than should I just bend the frame and equip whatever cassette/hub/wheel/etc. I can afford?

This is my first time totally building up a bike, and I'm totally worried about screwing everything up (oh god the time sink this will become...).

I "spread" a 126mm 7 speed Centurion to 130mm and now run a 10 speed cassette with no problem. If you use Sheldon's method and check to make sure each side is "spread" equal, your wheel will still be in center so no brake issues. I also aligned the dropouts on mine because mine were out of line to begin with and now I can ride "hands free" quite easily! Hope this helps a little.

Do a search on this subject, there are plenty of posts. I use the threaded rod an nut method which has worked fine on 3 steel frames. My LBS just squashes the 130 wheel in the 126 spacing which can be done but can be an issue if you have to change a flat and are not as strong as the mechanic to get the wheel off and on.

You don't even really need to cold set the rear triangle to 130 mm, just spread the dropouts by hand whenever you install the wheel. Eventually, the dropouts will spread out to close to 130mm.
