So my bike has 126mm spacing, steel frame. Anywho, I was thinking of putting a 130mm freehub on the back and running a 7 or 8 speed casette. Bike shop a couple of times suggested going to 135 mm instead, but I don't know if I really want to. I have already gone from 120mm to 126mm spacing (re-bent the stays once) and I have no troubles putting in a 130mm single speed wheel on.
Any real reason why I should have to go to 135mm? I really just want 130mm spacing, then I don't have to permanently bend the stays to use the wheel.
Bike is a '71 Schwinn Super Sport. I use to run a 5 speed freewheel, but I was an axle bender.
