Advice for getting Campagnolo Zonda wheelset on a 2000 8 speed shimano rsx So I have an old road bike and instead of coughing up cash for new one I've decided to just start upgrading parts now and slowly build a better custom bike, one piece at a time. 

My bike currently has shimano rsx group set minus the shifters which were replaced with Shimano sora flight deck triple shifters. Old stuff I know!

Triple ring in front and 8 in back.

So I wanted to get this wheel set: http://www.wiggle.com/campagnolo-zonda-clincher-wheelset/

But it says compatible with 10 and 11 speeds.

How can I get this working on my bike?

without having to get a newer crankset (10 or 11 speed) or group set. I want to get a new group set but rather get wheels first to make riding more fun and fast.

Any advice is mush appreciated! Relatively new to upgrading.
Campagnolo (not Mavic) make a Shimano-compatible cassette body for the Zonda. 

It's the same unit as they also use on the Fulcrum wheels and it will take a genuine Shimano cassette directly.

Whilst the cassette body is advertised as 10/11s, it will work fine with 8s - the spline pattern on the inside of the cassette sprockets is the same.

You will need to use the supplied spacer under the cassette in order to lock it firmly in place.
