Sora 9 Speed on Campagnolo Cassette
Yes, it works. I ran a Campy hub and cassette with Shimano DuraAce shifters and derailleurs with no problem. Chain was usually SRAM or Shimano. 9 speed is wonderfully versatile in this regard! Just make sure your rear derailleur hanger is straight. That tends to exaggerate tolerance discrepancies more than anything else.
