A friend just bought a new bike with Chorus components. Her previous race wheels used 8 speed Shimano so she wants to change the cassette to 10 speed. Is it possible to simply change the cassette body to a Campy one(Is that the right name?...Free hub?)? Are the cassette widths the same?

I'll check my copy of Zinn when I get back home but if you could help out, that'd be great.
Thanks.

incompatability

The short answer is no. The spacing in the shifter must match the cog spacing on the cassette, 8 to 8, 10 to 10 etc. Also the Campagnolo and Shimano hub/cassette spline patterns are different, you cannot slide a Campy cassette onto a Shimano freehub. Also a 10 speed cassette needs a 10 speed chain. You could upgrade the the entire drive train, upgrade the shifters, and maybe rebuild the rear wheel to make it work but the cost would be excessive.

She just needs to buy a conversion cassette. If the wheel uses the older 8 speed hub it will have a raised notch on the outside edge of the cassette body which will prevent the conversion cassette from seating all the way. You can either grind the notches down with a dremel as I did or you can have your LBS replace the cassette body with a new Shimano cassette body.

Either this one - http://www.excelsports.com/new.asp?...sion+Cassettes&vendorCode=AC&major=1&minor=10

or this one - http://www.excelsports.com/new.asp?...e+10+Speed&vendorCode=WHEELS&major=1&minor=10

will work. Here's the one I use - http://www.excelsports.com/new.asp?...d+Dura+Ace&vendorCode=WHEELS&major=1&minor=10

These cassettes work really well with Campy drive systems.
