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.
