126mm rear hubs sometimes need a little more room for a Sunrace 7-speed, just depends on the hub. The difference maker for me can be axle length. I like a little more axle showing on each side of the locknut (4mm) than Sheldon does (1-2mm). If I have that much room and the freewheel/chain will clear the frame, use of a 7-speed is feasible. If the bike is going to be loaded down in the rear with groceries or whatever, a 6-speed may provide a more sturdy axle. And yes, you usually have to redish when changing hub spacing.
