campy freehub
 

Hi, is it possible to use a fulcrum racing with campy cassette with sram groupo, everything in sram except cassette in campy??

Well based on their website, Jtek doesn't make one for that.

Your only route may be to swap the cassette body over to Shimano and get a Sram cassette for it. Obviously not the money you were looking to spend.

cause I can buy a fulcrum racing one, very good price but the freehub is campy and I have a sram groupo....

Since you have a SRAM grouppo, I am going to assume you already have a cassette. Changing a cassette body is an easy job, all you need is a 5mm hex key and a 17 mm wrench, a 5 minute job. If the wheel has a campy cassette on it already, you could sell it. If there is no cassette, the new cassette body would probably cost less than a cassette

yes, but the shimano freehub for fulcrum is about 80$..

While it is true that the shimano freehub body is pricey, buying one gives you access to a much wider range of cassettes from both SRAM and Shimano. I don't think a Campagnolo cassette is going to be any cheaper than the freehub body

Why you dont try the combination and let us know? I read that campagnolo brifters with sram rd and shimano cassette works fine. Maybe the combination u want it works fine also...
