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 increases 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 a weight reduction of 8 grams compared to the previous CCD AERO version.
Titanium Hardware: The rear of the cage is equipped with new black-finished titanium screws, which help keep weight down and give 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 the 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 an optimization of the ultra-light carbon fiber plate thicknesses by 33% 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, planning for the addition of 2-4 extra links compared to the standard length.
Longevity and Lubrication: The robust design features full-ceramic bearings protected by special 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 totally 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.
