I've just gotten back into cycling after a 13 hiatus. I'd like to upgrade my derailures to newer 9 or 10 speed. Here are the bike specs
1992 Bianchi Alfana (new in 1992 $975) Nisi Laser Rims (tubular) American Classic Hubs (rear is 130mm, wheels are hand built $350) 7 spd cassette Hyperglide chain Shimano 105 components.
I know that I will need to replace the chain, but what about the rear hub, will that need replaced or just re-dish the rear wheel? I'd like to switch to Camy components with ergo shifters.

The easiest is to use 8 of 9 shimano 9s cogs, with 9s spacers, get some 9 or 10s ERGO and a Campagnolo rear der and you will be set. You cannot put a 8/9 or 10s cog onto the rear wheel but as I said, can use 8 cogs, spaced to 9s...which is completely compatible with Campagnolo 9 or 10s ERGO(of course, you will have to set the rear der so you will only have 7 'click's but that is not big deal).
If the freehub body of the rear wheel is set for shimano 8s, then use a shimano 9 or 10s cogset, chain, samo for the ERGO and rear ders...all else is compatible.

Campy and Shimano cassettes have different splines, so you can't exchange that blindly. Shimano 8 and 9 cassettes go on the same freehub, but S7 is a shorter one, I'm not sure about S10. If I recall correctly, Campy 9 and 10 go on the same freehub, but C8 and C7 are different. American Classic offers its current hubs with a choice of Campy or Shimano splines on the freehub -- you might be able to exchange just that part, which saves you the cost of the spokes and redoing the wheel. Try mailing them about it.

Short of disassembling the entire rear wheel, here is the info off of the smallest cog on the freewheel-
Sachs Maillard LY 91 Made in France 12
The 12 is the tooth count the rest I don't remember if the freewheel is Sachs or not.

Freewheel is the operative word. To upgrade you will need a cassette rear hub which can be either Campy or Shimano (spaced appropriately), assuming the rest of the drivetrain is Campy. The good news is that with 130mm spacing you will be able to get the full 9 or 10s after the upgrade. The bad news is that you will have to rebuild the wheel with the new hub.

I think he can go up to a 24 speed with a Sachs Maillard late-production freewheel because the spacing is perfect 5 mm between cogs. Early 1990's Sachs-Maillard are very sought-after freewheels because they allow indexing on freewheel bike(s).

Right, but won't he then have to find an 8s ergo shifter to go with it, along with the freewheel itself (apparently known for its axle bending qualities)? I think he's best off changing out the hub and getting the pain over with quickly.

If it's Campag, it's easy. 1999 or later ergo, converted to 8s, any Campag rear der, a 7s freewwheel, Sachs or DA...8s chain, go ride.
So do I understand correctly that I could purchase a current Mirage or Veloce Ergo set & convert them to 8s? I have an old 7s Cannondale for which I have a nice set of tubulars that I was thinking of converting to a crashterium bike, and this just may make it possible...
