When speed meets refinement, and engineering embraces elegance — the result is the Nova Ride Carbon Ceramic Oversized Derailleur Cage. Meticulously engineered in France, this drivetrain upgrade is not just a component but a performance enhancer for discerning cyclists who demand the best from their machines.
Designed for Shimano’s most respected 11-speed road groupsets — 105 R7000, Ultegra R8000 series, and Dura-Ace R9100 series — the Nova oversized derailleur cage delivers a significant reduction in drivetrain friction, elevating both efficiency and visual appeal. Whether you're chasing podiums or carving mountain switchbacks, this upgrade ensures every watt of your power is transferred more cleanly and efficiently than ever before.
At the core of this performance masterpiece is a rigid, feather-light carbon cage, holding two oversized 7075 aluminum pulley wheels — 14 and 17 teeth — that guide the chain with absolute fluidity. Unlike conventional plastic pulleys that wear quickly and create drag, these 7075 alloy pulleys with full ceramic sealed bearings glide effortlessly and are built for longevity. The ceramic bearings are fully sealed and protected by anodized alloy covers, making them not only corrosion-proof but also virtually maintenance-free — even in the harshest riding environments.
This cage has been intelligently crafted for real-world performance and compatibility. Whether you're running Shimano's mechanical or Di2 11-speed systems, the Nova cage slots in seamlessly — provided you’re not using clutch-style or 12-speed derailleurs. The weight of just 68 grams makes it one of the lightest oversized systems available without compromising on strength or durability.
Key Compatibility:
✅ Shimano 105 R7000 Series
✅ Shimano Ultegra R8000 / 8050 / 8070 Series
✅ Shimano Dura-Ace R9100 / 9150 / 9170 Series
What Sets It Apart:
Ultra-Light Carbon Cage: Adds structural rigidity without adding weight.
Oversized 7075 Alloy Pulley Wheels (14T & 17T): Increases chain wrap and decreases articulation angle, improving efficiency.
Full Ceramic Sealed Bearings: Deliver superior rolling performance and are fully rust- and corrosion-proof.
Zero Maintenance Design: Engineered to reduce the need for servicing or replacement, even over thousands of kilometers.
Enhanced Aesthetics: Adds a sleek, aggressive visual punch to your rear derailleur setup — because performance should look good, too.
Installation Guidance:
New Chain Required: Add 3–5 links to your current chain length to accommodate the longer cage.
Maximum Cassette Size: 32T recommended for optimal shifting and clearance.
Short Cage (SS) Default: Delivered in SS version; for long cage (GS) derailleurs, an adaptation guide is available:

Important Compatibility Notes:
⛔ Not compatible with:
Shimano Ultegra RD RX800 & RX805 (clutch-equipped)
Shimano 12-speed groupsets (Ultegra R8100 & Dura-Ace R9200)
Older Shimano 11-speed series (Ultegra R6800 & Dura-Ace R9000)
Mixing 105 with Ultegra/Dura-Ace 12S or 11S is NOT supported despite similar aesthetics
This product is precision-matched for Shimano 11-speed road systems only. Mixing it with incompatible derailleurs, even those that look similar, will result in poor shifting performance and potential drivetrain damage.
Final Word:
Whether you're chasing KOMs, sprinting to the finish line, or simply seeking the smoothest drivetrain possible, the Nova Ride Carbon Ceramic Oversized Derailleur Cage is your weapon of choice. It’s more than just a component — it’s a commitment to riding smarter, faster, and longer with fewer mechanical worries and more confidence in every pedal stroke.
