126mm / 7 speed is totally fine. You can get modern HG cassettes for it or HG style freewheels.
Even a 120mm spacing is fine- you can get a Suntour ultra6 freewheel and still be able to use 7 speed STI brifters.
So, where can I find new modern 7 speed cassettes that aren't crazy wide gearing? I haven't been able to find any thing like a 13-23 7 speed new for quite a while now. Everything seems to got up to 28T and larger. Not what I want on my vintage race bikes.
