Potenza rear derailleur 11-speed with HO geometry -2018-

The mechanical Potenza 11™ groupset is the aluminium version in the top segment of Campagnolo’s high-end road bike groups. Apart from the material, the Potenza 11-speed rear derailleur features almost all technical highlights of its bigger siblings Super Record, Record and Chorus. Thus, it guarantees the same shifting precision as well as an equivalent level of performance. The revised Potenza 11-speed rear derailleur keeps up with the times and features the Campagnolo HO geometry (Hydraulic Optimization) to optimize shifting performance in combination with modern disc brake frames. Thanks to the special shape of the upper derailleur body, Campy’s 11-speed HO rear derailleurs are compatible with all quick release skewers and thru axles available on the market. Besides, it facilitates wheel replacement significantly – an advantage even riders of traditional rim brake systems will benefit from.

Details:
· Campagnolo HO geometry (Hydraulic Optimization), to optimize shifting performance in combination with modern disc brake frames
· Completely new design: The new shape of the external components enables the rear derailleur to move according to a different angle and the new internal design keeps the chain nearer the cassette to ensure better power transmission, greater and more secure traction, a better chain/sprocket interface and greater durability of components subject to wear and tear.
· Embrace Technology™: A special chainring positioned inside the gear body allows the component to move along a trajectory that perfectly follows the curve of the sprockets
· Upper derailleur body made of fibreglass reinforced technopolymer for low weight and high resistance
· Redesigned pulleys with bushings for precise cage alignment
