This is an excellent derailleur with the tiniest imperfection in the clear coat on the bottom edge of the outer cage. Although it is not designated as such, this derailleur has the exact same cage as the later version that has STD+CT stamped on the inside of the cage. This means that Campagnolo designed it with the intention of eliminating compact derailleurs altogether and producing just one derailleur that will work properly with either a standard or compact crank.
