looks like it is Campagnolo compatible but i don't know the exact designation for this particular one.

Less is more.

So if it is the case, I guess I can buy a Shimano hub and replace that one.
I am new to all this.
Thanks.

Is it a Mavic Aksium?

It looks like their campag freehub.
Theyre not normally a very robust wheel, so you might be able to find a dead shimano version wheel at your lbs and get the freehub off it.

Don't bother trying to get a campag 10 cassette and making it work with your I presume shimano system.

Thank you all.
It is Campy hub!
