Developed by expert French engineers and manufactured using high-grade racing materials, this oversized pulley system redefines how smoothly and efficiently your bike shifts — delivering a tangible edge whether you're sprinting on flats, climbing aggressive gradients, or attacking switchbacks with explosive cadence.
🛠 Engineered for the Next Generation of Shimano 12S Performance
This Nova Ride 12-speed-specific model is purpose-built to match the design and functionality of Shimano’s most advanced electronic road groupsets:
Shimano Ultegra Di2 R8100 / R8150
Shimano Dura-Ace Di2 R9200 / R9250
With carefully optimized geometry and compatibility tailored exclusively for Shimano 12-speed Di2, this system guarantees precise chain articulation and optimized chain tension across the entire cassette range — up to 34 teeth, making it ideal for both elite racers and high-performance endurance riders.
⚠️ Compatibility Notice:
This derailleur cage is not compatible with:
Shimano 11-speed drivetrains (e.g., R8000, R9100)
Shimano 105 Di2 12-speed (newest mid-range 12S series)
🔧 Built from the Finest Materials in the Industry
At its core, this oversized derailleur cage system is a showcase of premium material science and cycling innovation:
Carbon Fiber Cage: Ultra-lightweight, rigid, and sleek. Maximizes power transfer while keeping weight to an absolute minimum.
CNC-Machined 7075 Aluminum Pulleys: 14T (upper) and 17T (lower) oversized design significantly reduces chain articulation, improving drivetrain fluidity and watt-saving efficiency.
Full Ceramic Sealed Bearings: Immune to corrosion, ultra-low friction, and extremely durable. Unlike conventional steel or hybrid systems, these bearings maintain peak performance without lubrication or servicing.
Anodized Alloy Bearing Covers: Defend the core from dust, grime, and water ingress, extending the component’s lifespan even in adverse weather conditions.
💎 The Nova Ride Advantage
Every detail is designed to reduce friction, increase power efficiency, and simplify long-term maintenance. Compared to conventional stock derailleurs with plastic pulley wheels, the Nova Ride system offers:
Lower mechanical drag
Reduced chain wear
Enhanced aesthetics
Extended durability with no performance drop-off over time
This oversized pulley design works in synergy with Shimano's 12-speed electronic shifting logic, enabling lightning-fast gear changes with minimal resistance — giving you smoother transitions and an unmistakable road feel.
📏 Technical Details
Weight: Only 68 grams — ultralight without compromising structural integrity.
Cassette Compatibility: Optimized for Shimano 12-speed setups with a maximum recommended 34T cassette.
Installation: Plug-and-play with factory Shimano 12S rear derailleurs (R8100/R9200 Di2). Chain length may need to be slightly increased depending on your gear ratio.
❗ Important Compatibility Reminders
This model is precision-tailored for:
✅ Shimano Ultegra Di2 R8100 / R8150
✅ Shimano Dura-Ace Di2 R9200 / R9250
And not compatible with:
❌ Shimano 11-speed systems (Ultegra R8000 / Dura-Ace R9100)
❌ Shimano 105 Di2 12-speed
❌ Mechanical or clutch-equipped derailleurs
Despite some visual similarities, each Shimano group has subtle yet significant mechanical differences. Using the wrong cage model can result in poor shifting performance or drivetrain failure. Always confirm group compatibility before installation.
