I'm hoping to upgrade from 7-speed early Chorus index shifting
to an ergopower 8- or 9-speed drive train including new wheels.
Can anyone tell me what the rear dropout spacing needs to be
for 8- and 9-speed Campy hubs (are they the same?) and whether the
dishing is worse for 9-speed than for 8? Are there advantages to
going with 8?
Thank you.

The dropout spacing is the same. Only real issue is cost.

8 speed hubs are no longer produced. And you cant put a nine speed
cassette on 8 speed hub {with shimano you can}.

Just built a 9-speed Record.

Dropout is standard 130mm. Dish is the same as 8-speed.

The width of the cogset is slightly wider (1-2mm) and places the
smallest cog closer to the dropout. Even on my Cannondale frame, this
hasn't been a problem.

The cogs are thinner and closer spaced. In fact, they are now almost
exactly the same spacing as the Shimano stuff.

The advantages with the 8 are a thicker cog and more industry standard
parts. The chain, derailleur, and the hub are specific to the 9-speed.

I have a feeling that the 9-speed will soon become standard, so it might
not be too bad a few years down the road.

The cost difference is only about $200 MSRP and lower in actual retail.

Since the Chorus and the Record are almost exactly the same design with
just different materials in places (steel vs ti) you can easily upgrade
to the Record stuff if you so desire. I truly recommend the Record rear
hub. It is significantly lighter than the Chorus. Best bang for buck
in the upgrade. The Record BB is probably the next in line.

One thing I really like about the record hubs is the grease port. Makes
keeping the stuff running easy.

Anyway, thats my story.

Chris.
