What cassette for Mavic Cosmic Pro

Djhep6 · Aug 5, 2012

Hi all.
Can anyone tell me if it is possible to fit either a Shimano or Campagnolo cassette to a Mavic Cosmic Pro hub. (see pictures)

I have a brand new set of these wheels which are gathering dust and would love to put them to use on either a Campag Chorus or Campag Athena 8 speed setup.

Thanks in advance for any help.

All the best.

Dave.

It looks like a hyperglide shimano spline to me but early campag (8 & 9 speed) looked similar I think ?

from Sheldon Browns site • Campagnolo: not very compatible
Campagnolo 8-speed cassettes used a slightly different spline pattern from the current pattern used for 9-and 10-speed systems.
8-speed Campagnolo cassettes will not fit on newer "9-speed" and "10-speed" hubs.

9- and 10-speed Campagnolo cassettes will not fit on 8-speed hubs.

It is theoretically possible to upgrade Campagnolo 8-speed hubs with newer cassette bodies, but in practice the parts don't generally seem to be available.

It looks more like Campag 8 to me.
All the splines look pretty equal in size.

Its def not Campag 9-10, and i think some of the later 8 is different again, but i'm no expert.

One eyed jim might be worth a PM to confirm...

I agree they are all equal so campag 8 it should be , now just get hold of a cassette for a test fit before purchase ! Knowing the even poorer availability of older mavic parts in my country it will be near impossible to get any other freehub body!

I used to have a pair of these. It's campag 8.

Won't run anything else - but Campag 8, Sachs and Dura-Ace 8 spacing was the same so will run on plenty of mid-90s configurations.

I bought a new Campag 8 speed loose cog cassette recently.
Unfortunately it won't fit on the Mavic hub. (the hub dia is quite a bit larger than the hole in the cassette).

Are there different types of Campagnolo 8 speed cassettes available?. I'm thinking maybe the older type were different with a larger dia. Would that be right?.

(The splines on the Mavic hub are definitely all equal in size).

Thanks for all the help so far.

If you bought an 8-speed Titanium cassette it'll have 9-speed splines which are deeper.

For reference, here's a good summary of the various spline patterns used by Campag:

As you can see, your freehub body is the original 8-speed type.

OE Jim.....
Thanks for the link.
That definitely confirms that the hub is compatible with the original Campag 8 speed type cassette.

Does anybody know if these are still available, and if so what would be a good place to source one?.

Dave.
