SHIMANO Dura Ace RD-9070 Jockey Wheel Set
Restore the pinnacle of shifting performance and drivetrain efficiency to your high-performance road bike with the genuine SHIMANO Dura Ace RD-9070 Jockey Wheel Set. As a crucial component within the Transmission system, these spare parts are engineered to the exacting standards of SHIMANO´s top-tier Dura-Ace line, ensuring your bicycle operates at its absolute peak. This set is the definitive choice for discerning cyclists looking to maintain or refresh the crisp, rapid, and reliable shifting action that defines the Dura-Ace experience.
Key Benefits:
Experience a significant restoration of your rear derailleur´s function. This jockey wheel set is designed to bring back the flawless gear changes and silent operation you expect from a premium groupset. By replacing worn or gritty pulleys, you eliminate chain hesitation and ensure each shift is instantaneous and precise, whether you are climbing a steep grade or sprinting for the finish line. The advanced bearing system dramatically reduces friction, contributing to a more efficient transfer of power from your legs to the road, saving valuable watts and enhancing your overall speed and endurance. Built for longevity, these pulleys are designed to withstand thousands of miles of rigorous use, offering consistent performance ride after ride.
Main Features:
This essential replacement kit includes both the guide pulley and the tension pulley, forming a complete system for your rear derailleur. The standout feature is the integration of ultra-smooth, high-quality sealed precision bearings. This sophisticated design provides two major advantages: it ensures a silky-smooth rotation with minimal resistance for maximum drivetrain efficiency, and it effectively shields the delicate bearing mechanism from contaminants like dust, water, and road grime. This sealing is critical for maintaining performance over the long term and reducing the need for frequent maintenance. As an authentic SHIMANO component, this set guarantees perfect compatibility and seamless integration with your existing Dura-Ace derailleur, preserving the integrity and performance of your entire system.
Jockey Wheels and Technical Specifications
This set consists of two 11-tooth pulley wheels, specifically engineered for the SHIMANO Dura-Ace 11-speed series. The guide pulley (top) is responsible for steering the chain with precision onto the correct cassette sprocket, while the tension pulley (bottom) maintains optimal chain tension for smooth and secure operation across the entire gear range. These are a direct replacement for the original pulleys found on Dura-Ace RD-9000 (mechanical) and RD-9070 (Di2) rear derailleurs.
