My Miyata spaced at 126mm works just fine with a 130mm wheel even with modern, tightly spaced 9sp indexed gearing. In fact, my tandem bike somehow seems to shift fine with 7sp indexed shifters. I'm pretty sure it's 110mm or something and I've got a 126mm wheel jammed in there. I know this one should be cold set, but it shifts fine and it's a rusted old junker anyway... So yeah, just shove the wheel in there and if it shifts fine, don't worry about it too much unless it looks like it's off to one side for some reason.
