Campy 9-speed cassette

I enquired a few months ago, but didn't save the response. I have a
Campy Record 9-speed cassette (circa late 90's) that just started
skipping with a chain replacement. I believe this is an Exa-drive. The
cogs have four tabs, equally spaces. 3 tabs are identical, the fourth
is narror and its shoulders are of different heights. Does anything
exist that is compatible with the free-body splines?

One tab is 'stepped' right? That's the current pattern for
9-10-11 systems.
Campagnolo 9 cassettes are still current, unsure about
aftermarket.

Yes, the narrow one is stepped. Does this mean I could use a current
Veloche 9-speed cassette on this Record freehub? Would the spacing
be the same?

Thanks,

Yes. And once you have a CrMo nine cassette you'll have the
spacer set to mix-n-match sprockets using nine and ten
sprockets. The expensive cassettes are spidered.

Joe, please forgive me if you're way ahead of me on this, but I've had this problem to some extent just about every time I've changed chains.

1. Ride it 100 miles, and by then the chain and cogs will wear in together and stop skipping.

2. Is your top jockey wheel close to your cogs? This can cause skipping with a new chain. Can you maybe take take a link out of your chain to see if that moves the top jockey wheel farther away from your cogs?

Just my $.02. If I'm wrong, it wouldn't be the first time!
