The CCD AERO EVO rear derailleur cage combines the technical know-how of the AERO range with the premium finishes and rigorous standards of the EVO line. The design, shaped by airflow, adopts a radical approach where aesthetics are entirely at the service of efficiency: the goal is to maximize friction reduction and ensure absolute aerodynamic precision. An essential, racing-looking component that underscores the absolute priority of this range: uncompromising performance.

Features and Innovations:
EVO Finishes: While maintaining its iconic aerodynamic architecture, the model boosts performance and finish level thanks to CCD EVO components. The integration of EVO pulleys, the application of a matte protective paint, and the use of black titanium hardware allow for an 8-gram weight reduction compared to the previous CCD AERO version.
Titanium Hardware: The rear of the cage features new titanium screws with a black finish, contributing to weight containment and providing a premium aesthetic. The dark color facilitates visual integration with the bicycle, while titanium ensures an optimal weight-to-strength ratio.
Redefined Aerodynamics: Reduction of aerodynamic drag with particular attention to optimizing frontal impact and smoothing rear airflow, thanks to the unique airfoil profile design (closed at both the front and rear).
Structural Optimization: The addition of aerodynamic material, aimed at not excessively increasing overall weight, required a 33% optimization of the thickness of the ultralight carbon fiber plates in key areas, maintaining durability unchanged.
Maintenance-Free Performance: Full-ceramic dry bearings ensure free rotation, reduced friction, and a total absence of grease. The contact between the balls and the retaining cage, both entirely made of ceramic, extends the component's service life by reducing wear.

Installation and Maintenance:

Wheel Compatibility: This product is NOT compatible with the Roval 321 Disc rear disc wheel.
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, chain replacement is strongly recommended at the time of installation, 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 lifespan over time and minimize wear compared to standard plastic pulleys. The system operates entirely dry and minimizes the need for intervention: no grease is required.
Cleaning: Thanks to its 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 work dry, NEVER apply any type of lubricant.
