OK the bike these fabulous hubs are going on is currently mostly Campi but with a DA Integrated 8 RD and 8spd DA SIS shifters. However the rear wheel in the bike right now is a......Campi hub with an 8spd cassette! I got so caught up in worring about how to make these new hubs (soon to be wheels) work on my other bikes I forgot I will be taking a perfectly good set of wheels off this bike can take a Campi 9spd cassette. I will have to triple check this of course but I am certain these hubs will work on atleast some of my 9spd bikes.
Nope.
With the move to 9 cogs Campagnolo changed to deeper splines (to allow alloy freehub bodies which don't indent) and made the freehub a bit wider.
That means you can't put a 9-speed cassette on an 8 speed hub.
Compatible 9 speed freehubs exist but getting one may require buying an old 9 speed hub, swapping, and selling the left over 8 speed hub which results.
( I upgraded my 1996 Chorus 8 speed hubs to 9 cogs after Campagnolo discontinued my favorite 8 cog cassette )
