My ’74 Raleigh Supercourse frame came with a 130mm rear fork spread. I suspect it was cold-formed at one point as these frames originally came with a 126mm spread. I recently purchased an older 27" wheelset that has a 126mm spread. I realize that by inserting spacers between the forks and the hub, I can make up for the 4 mm difference. However, will there be any problems when shifting with the rear derailleur with this odd setup?
I think it originally had 120mm rear spacing. It's just as easy to reduce the spread as it is to increase it if you follow Sheldon Brown's instructions. All you need is a 2X4, a ruler and a piece of string and you can correct any misalignment while you're at it.

You should be able to just slip the wheel in and tighten up the skewer with out any modifications for the 2mm difference. I've gone the other way plenty of times and could only imagine that pinching down the 2mm would be even easier.
