    I've inherited a set of these but can find little on line about them. Think they're 2005 maybe? Anyone know anything about them? I have no other Campy stuff so I'd like to flog them but need to get some knowledge first.

    My google fu has failed me. I'm guessing they're not anything super fancy, have looked through Campy catalogues and found references to "Ultra drive" but nothing definitive.

    I believe 'Ultradrive' was a type of chainring as opposed to chainset. Supposedly designed for faster, smoother shifting with the front mech. You're probably right about the year since 2006 was the last year they used square taper bottom brackets.

    Thanks for that happytramp, I started to wonder that. Grand so, had a check on eBay and they're not anything special. Will remove and throw into ads.
