if you cold set your frame to widen the spacing...

be careful. it doesn't take much force to spread the rear dropouts. I way overdid mine. Tried to undo it, now the thing looks like a bad dream. I might try to get it back in line, but I'm pretty bummed right now.

It should be possible to get it back in shape... did you read Sheldon Brown's page on cold setting? Apparently it's not uncommon to need to do some corrections to get it to the exact right size and alignment. Good luck!

Yeah, be careful and move it each dropout in one direction only (outward). Don't over do it or else you'll have to bend it back and end up with distortions... Go 1mm at a time and check your progress often.

A simple solution that MIGHT work. I have an old Spec. Allez (their crit-style main racing frame in the mid 80's) with stiff Specialized proprietary tubing and 126 spacing. Fretting about a wider cassette/axel, one day I simply applied a surprizingly little pressure with my thumbs, and a 9 spd rear wheel slipped on. There was nothing to it. About 4 seconds of extra effort and I've enjoyed perfect performance since. Wheel removal out on the road is easy....worth a little experiment if you haven't tried it yet.

Yep! I do this on my aluminum road bike, that is I use a 9-speed wheel (130 mm hub) in the 126 mm dropouts, simply by squeezing them open a bit when I need to change the wheel. It's not safe to cold set an aluminum frame, but it seems perfectly safe to do what I do.

I asked about it on rec.bicycles.tech, and it turns out dozens of people do it with no problems at all, some for 10,000 miles+.
