Chorus components have long been the working man's component group from Campagnolo. The way it functions and feels is almost identical to the upper Record groups. This current version of Chorus features the black-out cosmetics, so now it looks similar too.
The Z-Shape cage has AFT - Anti Friction Treatment for smooth and quick shifting and works with both compact and standard cranksets.The pivot arm is of the super stiff M-Brace design variety. Upgrades from previous versions (aside from the cosmetics) include a modified front derailleur plate for quicker shifting.
