The Oversized Pulley Cage (OSPW) Carbon Ceramic Derailleur is specifically designed to optimize the performance of the Campagnolo Ekar 13-speed derailleur. Hand-assembled with the highest quality materials, this structure combines ultralight construction with extreme durability, ensuring more precise shifts and superior performance to meet the demands of professional and amateur cyclists. The sleek design integrates perfectly with the bicycle's aesthetics, adding a customizable touch of color.

Features and Innovations:

Reinforced Off-Road Structure: Compared to road versions, this specific variant features a carbon fiber cage with a 33% increased thickness. This structural optimization has been implemented to most effectively absorb potential impacts typical of gravel use.
Pulley Configuration: The system is complete with two oversized 7075 aluminum pulleys, respectively 14 teeth (upper) and 17 teeth (lower).

Installation and Maintenance:

Cassette: It is recommended to use a cassette with a maximum of 44 teeth to ensure optimal adjustment and shifting.
Chain: To ensure maximum performance, a new chain must be used at the time of installation, adding 2-4 extra links compared to the previous configuration.
Longevity and Lubrication: The design features sealed full-ceramic bearings protected by dedicated aluminum covers, designed to maximize lifespan. The system has been engineered to eliminate maintenance issues: it operates completely dry and does not require the use of any grease.
Cleaning: As the bearings are completely ceramic, there is no risk of oxidation. In case of dirt buildup between the covers and bearings during rides, a simple wash with water or degreaser is sufficient for removal.
Important Warning: As these are bearings designed to work dry, NEVER apply any type of lubricant.
