6 Speed Cassette on 9 Speed Hub

yenkee

Hi,

I'm considering upgrading my new rear wheel. Currently this has a 6 speed cassette but the replacement wheel I'm considering (second hand) previously had a 9 speed cassette on it. Would you know whether this would be an issue? or can I simply put my old cassette onto it without any problems?

I ask this as most wheels say 8/9 speed compatible? Does that mean that 8 or 9 speed are harder to fit (therefore you need to be more selective) and that most rear huns will take a 6 speed?

Thanks,

cant say that I know of any 6spd cassettes. it is most likely a freewheel rather than a cassette. So no it will not fit.

Also any hub that is 6 speed is not likely to have the same hub width. So the hub would not fit in the frame.

what do you need to change?

Hi Nick,

The reason I was considering this change was because I thought this would be an easy solution to converting my wheels to quick releases. Thought this would be easier than replacing the axles, reading around there seems to be a lot to consider when looking to change bolt-ons.

You could get a 7 speed cassette, a spacer that goes on the inside for 3 quid and just set it to ignore the 11T gear if you only have 6 on the shifter? Think 6/7/8 are the same width sprockets and spacing so indexing shouldn't be an issue. Or get a revoshift 7 spd shifter for 3 quid too for a really hi-tech upgrade

Forgot about axle width. Brute force should sort that....

make some interesting reading.

but 6 speed freewheels are easy to get and swapping an axle over is not that hard. Just the same as a hub service really.

Quick releases are not good, there is a reason a lot of top bikes go back to bolt on.

They are fine for many people. And many top bikes still use them.
