The new oversized pulley cage (OSPW) CCD EVO S is specifically designed to optimize the performance of 12-speed Shimano 105 derailleurs. Developed to maximize drivetrain efficiency, it ensures exceptional smoothness and a significant reduction in friction, while maintaining the highest technical and reliability standards.

Features and Innovations of the CCD EVO range:

Increased Rigidity: The new structure maintains the brand's technical DNA and has been optimized to offer superior rigidity and extreme durability. The unique and recognizable design is the result of careful and meticulous engineering in every single detail.
Increased Lightness: The design of the carbon cage and pulleys has been completely revised, both in the study of geometries and material thicknesses. The goal is to offer a modern visual harmony, while maximizing lightness and performance efficiency.
Optimized Aerodynamics: Based on developments from the CCD AERO model, the EVO version features a redesigned frontal surface and hardware, tested in a wind tunnel. This optimization improves air penetration and increases aerodynamic efficiency by 66% compared to the standard CCD model.
High-Precision Machining: The high level of finishing results from a new global approach to design. Geometries and thicknesses have been finely reworked, requiring a 200% increase in machining time to achieve superior quality standards.
Titanium Hardware: The rear part of the cage is equipped with new black-finished titanium screws, which help reduce weight and provide a premium aesthetic. The dark coloring of the structure facilitates visual integration with the bicycle, while titanium ensures an optimal weight-to-strength ratio.

Installation and Maintenance:

Cassette: It is recommended to use a cassette with a maximum of 34 teeth to ensure optimal adjustment and shifting.
Chain: To ensure maximum performance, replacing the chain at the time of installation is strongly recommended, adding 2-4 extra links compared to the standard length.
Longevity and Lubrication: The robust design features full-ceramic bearings protected by dedicated aluminum covers, designed to maximize longevity and minimize wear compared to standard plastic pulleys. The system operates completely dry and minimizes the need for intervention: no grease is required.
Cleaning: Thanks to the 100% ceramic composition, the system is completely immune to oxidation. In case of debris accumulation between the covers and bearings during use, a simple wash with water or degreaser is sufficient.
Important Warning: As these are bearings designed to run dry, NEVER apply any type of lubricant.
