The '08 Chorus front derailleur gets the same makeover as Record. It gets a standardized cage -- compatible with both 53/39 and 50/34 Campy cranksets. In addition, it gets a new body and a new inner plate design to improve shifting performance. The derailleur as a whole is more rigid, which gives notably superior shifting when you go from the small ring to the big ring. The front derailleur cage retains the front part of the CT model -- exactly where the chain touches when you shift from small to big ring. But the curvature and height of the rest of the cage is new, which is what makes it compatible with both standard and compact cranksets. Lastly, the inner plate has a new shape that gives the derailleur more oomph when you shift from small to big rings, again improving these upshifts.

The Chorus front derailleur comes with the same anti-friction nickel-plating treatment as the Record version. The central difference between the Chorus and the Record, in fact, is that the Record uses a carbon fiber outer plate, while the Chorus uses an alloy outer plate - a penalty of a whopping 15g!

The braze on version requires 7Nm to fasten the derailleur to your frame. The clamp-on version requires 5Nm. The Chorus QS is 85g for the braze on version.
