9-speed cassette with 8-speed hub?

[Lynn Monsanto]

Hi all,

I'm sure this this a frequently asked question but bear with me ;-). I have a couple wheels with
8-speed DuraAce hubs and I want to use 9-speed cassettes with them. Is there any way to convert the
hubs without rebuilding the wheels? The axle length is 130mm. My rear deraileur will handle the
9-speed cassette so I'm hoping all I have to do is replace a shifter plus the chain and do something
minor to the hubs (wishful thinking, I'm sure).

Thanks, Lynn

No conversion or wheel rebuilding necessary; 8 and 9 speed both use the same hub. All you need is
the 9 speed shifters and chain.

I agree with George. I have an 8-speed DuraAce hub with a 9-speed Ultegra 12-27 cassette, in
fact the rest of the components are Ultegra, and I've never had a problem since I got the bike 4
years ago.

As others have said, no conversion necessary, just take the 8 speed cassette off and install the 9
speed cassette and ride off into the distance.

If the 8s DA hubs use a lockring(hyperglide, not uniglide) then any shimano 9s casette will fit onto
w/o modification. If you are using an 11t first cog, then use a 1mm spacer first, then the
casette(perhaps).

If uniglide, you can install a DA 8/9s hyperglide freehub body on it.
