Carbon fibre immediately indicates a component's competitive spirit. So just imagine if the component in question is the very soul of the racing bike: the rear derailleur. The carbon front link says it clearly: the Chorus™ groupset is designed for racing. Available with a short or medium cage, to interface perfectly with double and compact cranksets.

I've used Chorus for over a year now having moved from Ultrega, I would have to say Campagnolo blows Shimano out of the water for build quality, looks and function. This groupset brings with it long lasting quality and to die for looks, but it is slightly overpriced compared the Jap brand.

I disagree! Campy blows Shimano out of the water.

Rated 4 out of 5 by Anonymous Smooth transition, solid product, looks great with a hint of carbon, but does not compare to shimano dura-ace.
