Hello! I have a few questions that hopefully the Campy Experts on these groups can help me out on:
My winter training bike is a mid-90s CroMoly frame Bianchi I upgraded with Campy triple Racing T and newer Veloce 9 speed shifters. The cassette/rear hub is the original 8 speed and works OK with the 9 speed shifters, I just have that extra "click". My other bike (Kestrel Talon) also has Campy triple Racing T and Centaur 9 speed shifters and I hope to eventually get a pair of Zipp 404 carbon wheels to race with on this bike.
Ultimately, I would like to have 9-speed cassettes on both wheelsets so that I could swap wheelsets between bikes. That's where my question comes in as far as advice on how to do this. The 8 speed gears on my current wheel has 8 notches to slide the gear onto the splines on the hub (I think it is called the EXA-Drive system). From pictures I have seen, it looks like newer 9 speed cassettes have a different spline pattern than the 8 speed. I can't tell from the photos whether these 9 speed cassettes would work on my 8 speed hub. Do I need to replace the 8 speed hub to work with all 9 speed cassettes? Are there different spline patterns between the different Campy 9 speed cassettes (e.g., Veloce and Chorus)? Zipp's website says that the 404 wheels are compatabile with all Campy 9 and 10 speed systems, so I definitely want to make sure I get the right cassette(s) to use on these wheels. The cassette I am seriously considering for its low range gearing is the Veloce 9 speed 13x28.
Thanks in advance for your help and advice! Andrew Hall Lancaster, OH

Snip using Campy 9 speed cassette on 8 sp hub.
It is not a straight fit on. People will say it is possible by filing away some bits on the hub/cassette,and it is then held on the hub by about 2 turns on the lock nut(the 9sp is lightly wider) - but is that really worth it? Another way is if you can get an older (yr 2000?) 9sp rear hub, you can take off the freewheel/freehub from that, and fit it to the 8sp wheel, and you then have a 9sp wheel. It may be more cost effective to just get a new wheel built up in place of the old one. All 9 and 10 sp campy cassettes have the same spline pattern, so there are no problems with swapping between wheels. Alan.

The 9 speed splines share the outside diameter but have a smaller inside diameter so they won't fit on an 8-speed freehub. Campagnolo built 9-speed frehubs which fit the old hubs (I swapped my Chorus 8 speed parts for Record-Ti 9-speed) although they're getting scarce (and therefore expensive - say $100 for a Chorus/Record part).
