7 speed cassette on 8/9 speed hub?
Can you mount a 7 speed hyperglide cassette on an 8/9 speed freehub?
I have a older road bike that came stock with 14 speed Shimano SIS and cheap wheels. I have broken several spokes on the rear wheel and am debating about rebuilding it or replacing it with a new wheel. I have a 7 speed freehub so I believe the frame spacing is 126mm OLD. The frame is a Raleigh technium frame (Al main tubes, steel fork and rear stays), so I think I would be OK installing a modern rear wheel with 130mm OLD.
What I don't know is if I can mount my old cassette on an 8/9 speed freehub, and if so do I need some kind of spacer?

Meaning what? The modern road bike is 130mm, the MTB is 135. This has nothing to do with the freehub body dimension though. The 7 speed body was shorter than that now used for 8/9 speeds.
You can get a low end (Altus?) 7 speed hub spec'd as an 130 or 135mm.
