Campy 8-9 cassette on 10 derailleur?(5 posts)

Campy 8-9 cassette on 10 derailleur?templecat
Dec 19, 2001 5:44 AM
There are some good deals out there on wheels with sub-10 rear wheels. Any probs with running a 8 or 9 cog cassette on a 10 speed derailleur? Is overall width a problem, or the spacing between the cogs that might trip up the system?

Or do you just adjust the derialleur high & low sets and go from there???


Only difference between 9 and 10 speed campy is...Cima Coppi

The width of the jockey pulleys. You can use your existing derailleur, but you must change out the pulleys to the wider width to accomodate the wider 9-speed chain or the even wider 8-speed chain.

That being said, there is also an issue of your 10-speed ergo levers (if your are using them), because 10-speed ergo will not work with 8 or 9-speed anything.

Now, if you are using 10-speed ergo, you can still get a wheelset with a shimano splined hub body, and get a Wheels Manufacturing 10 speed kit (found at Branford Bike, Excel and others), and you will not have to change out anything else on your existing drivetrain.

Definitely check out Branford Bike's Cassette index. They have everything imaginable for spacing kits, cassettes, individual cogs, etc:

If you have a 10 speed drivetrain, you should only use a 10 speed spaced cassette. The cog spacing on 8, 9 and 10 speed cassettes is substantially different.

Campy compatible freehubs will accept a 9 or 10 speed campy cassette. The splines and overall width are the same.

You can get a special cassette with 10 shimano cogs, spaced for campy 10 speed, but it may not fit all shimano compatible freehubs and it costs $130.

It's best to stick with wheels that offer a campy 9/10 freehub if you have a 10 speed drivetrain.
Campy rear hub is same for 9 and 10Blair

So buy a 9 spd rear wheel and swap the cassette.
