cassette questions

Daft question this maybe, but there's no information on the usual various websites about it.

Can I buy a new rear wheel with a 9 speed freehub and use it with my existing 7 speed setup ? I
assume all that is needed is to buy a 7 speed freehub body, transplant it onto the 9 speed hub, and
slap a 7 speed cassette on. Is this correct ?

Apparently a 7 speed cassette will fit a 9 speed hub but you will need a spacer (5mm?) to
fill the gap.

Yep! I've done this with great success.

It's even simpler.

Add one scrap spacer* behind your low gear and just slip your seven cassette on the new wheel.

The above assumes your seven is HG and the new hub is Shimano compatible

*taken from a dead cassette, usual price $0

I had to do this because of inability to obtain a 7 speed freehub at short notice. It is even easier
than you expect; a 7 speed cassette with a normal 7 speed spacer (from an old cassette) underneath
the largest sprocket is near as dammit the right width.

Yes, my current seven (freewheel) is HG. So I'll simply buy a 7 speed cassette for my 9 speed 105
hubbed new wheel, stick in a spacer as you've kindly suggested, and I'm there.

Some people (incl. Sheldon) are talking about re-dishing the wheel. Is this really necessary ?
Shirley the alignment of the cassette while it's on the hub does not effect the centre-ing of
the wheel.

That's if you start with a 7 speed wheel, take off the 7-speed cassette freehub and put the slightly
wider 8/9 speed one on. (and do appropriate spacer changing if you're not spreading the frame). If
you start with the wide freehub in the first place, no change.

cheers, clive

Thank you very much!
