Fitting cogs on Cassette

[AdrianS]

Just taken delivery of a new 9 speed Shimano HG 50 road cassette.
The smallest 4 cogs are loose. How should I fit them in relation to the other cogs on the cassette? Where do the ramps go in relation to each other?

Cheers for any advice!

I think all HG (hyperglide) cassettes are similar, if you look inside each sprocket theres notches, one of which is thinner than all the others so you should line them all up from that. When you come to put it on the wheel (whatever the bit the cassette mounts to is called ) one of the splines is narrower than the others so you shouldnt be able to fit them any other way

Hope thats of use, ive only replaced 1 cassette so far though

The Shimano site will have full documentation which should make it crystal clear. Well worth reading that to make sure.

Mr Jamie is right, they will only fit onto the freehub one way around - if you can get them on, they are correct

Sounds like you need the first 1mm spacer to be fitted before the cassette ?

No, not on a 9 speed.
You usually only need the 1 mm spacer if you are putting a 10 speed cassette on a hub which is 8/9/10 speed compatible.

Is that standard for 9 speed whilst 8 speed Shimano now only has 1 loose cog, down from I think 3.
