Campagnolo Athena Silver 11 Speed Rear Derailleur The Athena rear derailleur has the same geometry as the top-of-the-range 11-speed models, & absolute precision is the result. The outer plate wraps around the upper & lower bodies in aluminium, eliminating any possible play & making the overall structure of the rear derailleur extremely stiff. The result is fast & precise shifting in all the gears. The pulleys are specially designed to reduce vibrations & make the drivetrain perfectly quiet.
