So, I'm pretty new to this whole mountain bike thing. I've had a road bike for quite some time but have just recently acquired an 1997 Diamondback Sorrento as a commuter. It looks like sooner or later I'm going to want to either re-build the wheels or spring for a new wheelset, and probably the latter because the current wheels look like junk. It's got 7-speed Shimano Acera drivetrain, and looks like a freehub (it's got a splined lockring on the rear hub, this means freehub right?) So, question is, will any brand-new shimano rear hub be compatible with my sprockets? Or does 7-speed compatibility require going back in time?
You can use an 8-9-10 speed freehub, but you will need to add a 4mm spacer behind the casette. They are available from a number of suppliers or you could scavenge old spacers from a cassette and stack them to around 4mm.

If you're already springing for a new wheel, why not also a new cassette. Only $25 more and you get a brand new set of gears, in whatever ratio suits you. Wait...friction or indexed shifting? If indexed, stick with 7, although a 7 speed cassette, like everyone else has already said, will mount to any hub. If friction, the sky is the limit, although 9 is more than reasonable.
