Product Description
COMPLETELY BLACK, THE SUPER RECORD™ REAR DERAILLEUR BOASTS INNOVATIVE PARALLELOGRAM GEOMETRY. THE RESULT IS OPERATION WITH ABSOLUTE PRECISION. The carbon outer plate wraps around the metal body and executes the commands from the Ergopower™ Ultra-Shift™ controls with precision. Maximum smoothness for the cage pulleys made of anti-vibration material. Practically perfect from every point of view. This is the fulcrum of the 11-speed systems. The 11-speed rear derailleur has a forged aluminium upper body which works on an enveloping and oversized carbon fibre outer plate. The new form confers torsional rigidity which is 150% greater than the old design and contributes to the construction of a parallelogram with absolute operating precision. The cage pulleys are now made of a lighter material and reduce vibrations.
