8/9 speed freehub, 7 speed cassette?

intokyo

My question is, I have a 7 speed cassette, am getting a replacement rear wheel (Mavic GP4) which is built around an LX Hub model FH-M563. Seller says it's for 8/9 speed cassette.

Can I fit my existing cassette straight on or is there some kind of shim or spacer that must be used? Both parts are Shimano if that helps.

I really don't want to 'upgrade' to 8/9 speed for that will (I guess) involve replacing the shifters/cables plus new cassette......tight budget

The 7 speed cassette is narrower than a 8/9 speed hub. You can use a spacer to take up the slack though either something made for the purpose or a spare single cog from an old cassette.

Yep, as starsteve said, you need one of these:

Also check your hub dimensions.

as new MTB spec 8/9spd are 135mm while older 7spd can be 126/130mm

Fair cop - I should have looked at your location first! However, Shimano do an equivalent spacer which is likely to be more easily obtainable in your geographic location...

no worries

perhaps LBS will throw it in when they swap my cogs over. No harm in asking anyway.

Am I right in saying that a chain whip is all that's needed to actually remove and refit the cassette?

and a cassette tool and suitable spanner/adjustable wrench.
