Discover the Carbon Ceramic Derailleur designed for the Shimano 105 11-speed derailleur.

Features and Innovations:

Pulley Configuration: The complete system includes two oversized 7075 aluminum pulleys, with 14 teeth (upper) and 17 teeth (lower) respectively, equipped with full-ceramic sealed bearings.
Performance and Durability: Developed to offer an enhanced riding experience, the combination of lightweight and durable materials ensures maximum longevity over time without compromising efficiency.

Installation and Maintenance:

Compatibility Note: Despite visual similarities, the cage versions for Shimano 105 11v and for Shimano Ultegra / Dura-Ace 11v are different components and are NOT interchangeable with each other.
Cassette: It is recommended to use a cassette with a maximum of 32 teeth to ensure optimal adjustments 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 full-ceramic sealed bearings protected by dedicated aluminum covers, designed to maximize lifespan over time and minimize concerns related to technical maintenance. The system operates completely dry: no grease or lubricants are required.
Cleaning: Thanks to the entirely ceramic composition, the bearings are completely immune to oxidation. In case of debris buildup between the covers and bearings during use, a simple wash with water or degreaser is sufficient.
Important Warning: As these are bearings designed to work dry, NEVER apply any type of lubricant.
