Uncompromised performance.
With this goal in mind, Campagnolo® chose to equip the Athena™ 11s rear derailleur with a long rocker for maximum shift speed and precision even with the triple drivetrain.
ULTRA-SHIFT™ PARALLELOGRAM: designed to wrap around the rear derailleur bodies and increase the overall stiffness of the rear derailleur. Makes shifting fast, precise, and clean in all conditions.
LONG ROCKER: maximises triple drivetrain performance when using 12/29 sprockets.
PULLEYS IN SPECIAL RUBBER: friction reduction.
LIGHTENED UPPER BODY: weight reduction.
