The Campagnolo Record 11 speed rear derailleur has a forged aluminum lower cage with an enveloping and oversized carbon fiber outer plate. The parallelogram shape delivers 150% more torsional rigidity than the old design. Special lightened rubber pulleys rotate on ceramic bearings to ensure lower friction and longer life. Anodized aluminum fixing screw further reduces weight.
