Campagnolo Record LONG CAGE Rear Derailleur With CARBON CAGE NOS RARE VERSION

  

I had hopes of building a Record 3X10 bike, but alas things change. This is a brand new (installed on my dream bike), but never ridden long cage rear derailleur. This is the rare version with the black adjusting barrel. It will handle gearing from 53/30 to 30/11 and everything in between. This is an actual long cage, not a mid-cage posing as a long cage.
