Rear Cassette question

JayKingFunk

I know this might sound a bit stupid but if i have a shimano rear hub and need to buy a new cassette as i am replacing an old cheap wheel with a 7 spd cassette on it, does it need to be shimano??!

Would i be able to use the old 7spd shimano cassette for the time being on my new wheel? The wheel takes 8/9 so does this mean it will only take these cassette configurations??!!

I was looking at either the shimano XT 9spd m760 or the SRAM 9spd PG970

I assume that i would need to get a corresponding derailer, chain and gear changing trigger set? Could some1 tell me if i am right?! and if you guys think this is a decent set up for an XC rider on a budget???

Cheers in advance, J

If it is a 7sp cassette then yes you can use it on an 8/9spd hub as long as you use a spacer. as the free body is wider.

then for the 9spd you will need new cassette/chain and shifter as a minimum.

front mech and chain rings may be needed depending on what was fitted originally. the rear mech will just need re setting.
