If it's a Dura-Ace hub that's more than a couple of years old, or an Ultegra-105 level wheelset (WH-R7800,R7801,R600,R601, R5600, R560 IIRC) then it won't.

but campag is just a pain as there 10spd is totaly seperate entity to its 8/9spd systems :cry: shame as i really campag but if i get a 9spd set up and then wanna go 10spd its gona be costly :cry: :cry: :cry:
