Engineered with absolute precision and developed by seasoned French engineers, the Nova Carbon Ceramic Oversized Derailleur Cage stands as a remarkable upgrade for performance-oriented road cyclists seeking drivetrain efficiency, reduced friction, and an aesthetic edge. Every aspect of this system has been fine-tuned to elevate your riding experience — merging top-tier materials, mechanical efficiency, and design elegance into a single, standout component.
At the heart of this derailleur cage lies a rigid yet ultra-light carbon cage, paired with two oversized 7075-grade aluminum pulleys — 14 and 17 teeth respectively — to optimize chain engagement, reduce chain articulation angle, and ensure smoother, quieter transitions between cogs. These alloy pulley wheels are a significant step up from traditional plastic alternatives, eliminating premature wear and drastically extending component longevity.
Where most pulley systems fall short in longevity and rotational efficiency, Nova Ride’s full ceramic sealed bearings redefine the limits. Fully encased to prevent debris ingress, these ceramic bearings deliver ultra-low friction performance while remaining completely immune to rust and oxidation — even in the most extreme riding conditions. They’re not just high performance, they’re worry-free, demanding minimal maintenance across long-term use.
This version of the Nova Carbon Ceramic Derailleur Cage is specifically engineered to fit:
Shimano 105 R7000 Series
Shimano Ultegra R8000, 8050, and 8070 Series
Shimano Dura-Ace R9100, 9150, and 9170 Series
The cage is not compatible with clutch-based models such as the Ultegra RX800 and RX805 or any 12-speed systems — a deliberate decision to ensure maximum transmission precision for 11-speed electronic (Di2) and mechanical drivetrains. While the visual design may appear similar across Shimano tiers, cross-compatibility between 11S and 12S is strictly unsupported, underscoring the importance of precise model matching.
Performance Benefits at a Glance:
Increased Efficiency: The oversized pulley configuration reduces drivetrain friction, especially at higher cadence ranges, resulting in more power to the wheels.
Lightweight Advantage: Weighing only 68 grams, this system offers a noticeable weight drop without sacrificing stiffness or strength.
Aesthetic Upgrade: Beyond performance, it adds a sleek, race-ready edge to any performance bike setup with its carbon weave texture and CNC-machined alloy brilliance.
Built to Last: Ceramic bearings and anodized 7075 alloy construction resist environmental wear and corrosion.
Setup Considerations:
For optimal integration, Nova Ride recommends the installation of a brand-new chain, extending it by 3 to 5 additional links to accommodate the longer cage profile. Furthermore, the system performs best with cassettes up to 32T, ensuring crisp, clean shifting across the gear range.
In short, the Nova Carbon Ceramic Oversized Derailleur Cage is a power-efficient, visually striking, and mechanically superior solution for serious cyclists running Shimano 11-speed drivetrains. If you’re chasing performance gains without compromising reliability or aesthetic elegance, this upgrade is engineered for you.
