The Campagnolo Ekar 13S Pulleys are replacement jockey wheels designed to maintain clean, precise, and quiet gear shifting on a Campagnolo 13-speed drivetrain. They ensure the chain runs stably through the rear derailleur, contributing to a smoother feel in the pedals for both daily rides and longer tours.

As a direct replacement for 13-speed setups, these pulleys help maintain correct chain guidance for secure shifts, even under hard pedaling. This action reduces friction, potentially extending the lifespan of your chain and cassette within the narrow tolerances of a 13-speed system.
