nicklouse

any 9sp cassette will do. Sram or Shimano

how much do you want to spend?

camerauk

Not too bothered but just want one that will be smooth and not wear too quick

nicklouse

what is the hub? ( more accurately what is the freebody made out of?).

camerauk

Now you have got me I have no idea will have to have a look

camerauk

the hub is a shimano FH M475 if that helps

nicklouse

no probs as it is a steel freehub.

XT is best value/weight but some of the cheaper ones will last longer as there is more steel.

camerauk

would prefer to spend a little less as the XT ones look about £60
would like to keep it no higher than £40 if poss any ideas

thats a better price what is the main difference with the higher priced ones ie the Sram PG950, 970, and 990 is it just weight or is it smoother changing etc

nicklouse

generally weight. and how they are put together.

supersonic

Weight mainly. Sometimes a different finish. They also have an aluminium carrier body.

camerauk

cheers for replies I am not to bothered with the weight as I weigh over what I should and so dont think I would gain anything from a small amount of weight saved if that is all the real difference what would you recommend to buy

supersonic

Might as well get the PG950 for 16 quid at Merlin. Or a Deore.

camerauk

ok thanks will look at one of those is weight really the only difference

camerauk

sorry also can I get a 34t instead of a 32t and will it fit with same chain etc

nicklouse

you may find the chain is too short for all gears. (Big and Big cogs that you should not really use).
