Cassette body is different. An 8 speed cassette body will not fit on most new campy hubs. You may have to look on Ebay for 8 speed hubs or wheels.

 

QBP stocks a spacer kit that will modify an 8 speed Shimano cassette to Campy spacing. Then you can use any Shimano compatible freehub/wheel.

Most independent shops use QBP as a supplier.

 

In case your shop doesn't know what to order, you need the "red" spacer kit.

 

I have a set of 1997 Mavic CXP 11s or 21s can't remember model # with Mirage 8 hubs, been sitting around the garage for years.

 

An 8s cassette will work on a 9 or 10s body, but not the reverse. You're probably better off with a 9 or 10s hub because sooner or later you will not be able to replace 8s cassettes and derailers.

I am pretty sure Campy 8 speed splines do not fit on Campy 9/10 freehubs

Here's the best way to do this:

1. New Campagnolo 9/10/11 compatible rear wheel
2. 9 speed cassette with individual cogs and spacers (probably Veloce)
3. 8 speed spacer kit from Wheels Mfg. or Campagnolo

Remove all 9 speed spacers and one of the 9 speed cogs (usually the 26 or 28)

Replace the 9 speed spacers with the 8 speed spacers and install 8 of the 9 cogs

 

could i get away with putting a 9 speed cassette and change the chain..without having to replace the front and rear derailleur?

thank for your reply.

I've dealt with Nigel. Nice guy, reliable, he's got lots of stuff.

Campy 8 speed freehub bodies do not accept 9/10 cassettes and vice-versa.

I have the setup you referenced so I can run a lightweight set of newer wheels on my 8 speed Record bike (I also have a 10s Campy ride.) It works beautifully. I don't even have to do minor tweaks to the rear derailleur - it lines up perfectly.

If the OP is eventually going to convert his 8s bike to 10s, then that would be the way to go.

The downside is the expense. I can get 2+ 8s Sram cassettes (which also work with the Wheels Mfg. spacer kit) for the price of one Veloce 9s. The Campy 9s to 8s spacer kit is more expensive than the Wheels Mfg. one. And Shimano compatible rear hubs/wheels are all over the place at all price points. Campy, not so much.

 

The original guy (up top) has a campy 8 cassette and therefore the spacers that go with it - is the spacer kit 003 any different than these spacers? (I have exactly the same question and thanks for your answers so far).

 

I have NOS 1999 Campy Centaur hubs - same as the Record for all intents & purposes - 8 Spd. laced to Open Pro ceramic rims. Using an 8 Spd Miche cassette. Works great!

 

I know this is an old thread, but last night i took my old 8 speed Mirage cassette and fitted it to my 9/10 Record hubs without any problems. Just had to use a ten speed lockring. All this time i was led to believe it was impossible.

Goes to show, don't believe everything you read.

 

yes, some misinformation here...

8s and 9/10s use the same spline pattern, but the 8s splines are much shallower. 9/10 cogs will not fit on an 8s hub, because the splines are too deep for the grooves in the body. the reverse is *not* true however...

8s cogs *will* go on a 9/10s hub, but i strongly suggest you do not ride this combination. because the cog splines are much shallower than the body grooves, and the 9/10 body is now alloy (vs steel for the 8s body), there is not sufficient area of contact to distribute the load, and the short steel 8s splines will quickly gouge the freehub body.
