So I am looking to purchase used 10V ergos for a C&V build. I keep running into some strange descriptions. How many different versions of 10 speed ergos are there and how are they different?

Several...and interoperability was such a problem, and Campagnolo never documented it publicly in an easy-to-reference manner...that you have to ask.

In the space of ten years of 10 speed...the techs to know were "BB", "Escape", "QS", and "Ultrashift" (v1), and "Ultrashift" (v2). The items in quotation are stamped on the shifter head for 10s.

• MY2000 "BB" or "Carbon BB" or "BB System" was the original 10s shifters in 2000, these were originally Chorus/Record tier only...later on they filtered down to Centaur I think?
• 2004...Xenon (bottom tier group)...debuted an abomination known as the "escape" shifter mechanism....no one liked it, and no one wanted it--but Campy pushed it anyway to differentiate product tiers and make incompatibility.
• 2007 QS AKA QuickShift...these changed the FD ratio and the ratchet on the left shifter. Also less lever travel I think. Also in MY2007, everything Centaur and below got that abomination Escape shift mechanism.
• 2009(A) Escape dies, thank goodness; "UltraShift". No more g-springs. Bushings to save money on the cheaper parts, weaker ratchet detents IIRC.
• 2009(B) 11 speed for Chorus/Record/Super-Record....Athena appears as the bottom-of-the-top-tiers groupset.
• 2009(C) is when spare parts got very hard to find, as only assemblies were listed in the parts catalog. IIRC?
• 2011....Athena 11s and Centaur 10s and below...get gimped shifters (only one up and 3-down; as opposed to before where you would downshift 3 gears and upshift all of them)

All of which causes a tree-chart of incompatibilities which is very hard to keep straight. Which is why, in 2015, Campagnolo started stamping "A" and "C" and so on on the parts to denote compatibility....because this nightmare of product differentiation was very hard to keep straight in your head.

• 2010 right 10 speed Ultrashift levers got a new index disc with stiffer detents due to customer complaints in 2009
• 2015 the Ultrashift design changed

IIRC, all the 2010 Ultrashift levers run ball bearing main shafts. They're identical apart from right index cam, right front ratchet, black plastic/silver aluminum shift paddle, brake blade, the carbon fiber paddle sticker for Super Record, and 7g/pair saving rear ratchet discs for Super Record. Brake blades come in a choice of carbon fiber or aluminum, but otherwise differ only in finish, the two or three cut-outs for Record/Super Record, and group name printed on them.

Athena 11 speed Ultrashift came with silver aluminum brake blades and shift paddles. One of the 10 speed groups came that way too; IIRC Centaur aluminum (my 2010 Veloce levers are black anodized, and Centaur Carbon are obviously carbon fiber).

IIRC, 2007 marked the transition to black anodizing on aluminum parts.

10 Speed Campy qualifies as C&V????

It is almost 20 years old, introduced in 2000 for the 2001 model year.

I love the wealth of knowledge on this forum. That's an amazingly detailed answer.

I guess. I'm sure this dates me but I consider 6-speed freewheels and downtube friction shifting as the newest of C&V eligible stuff.
