Campagnolo Chorus 12-Speed Rear Derailleur: Precision and Versatility for Road CyclingElevate your road cycling experience with the Campagnolo Chorus 12-Speed Rear Derailleur, a masterpiece of Italian engineering designed for cyclists who demand flawless performance, versatility, and lightweight efficiency. As a crucial component of the Chorus 12-speed groupset, this rear derailleur brings top-tier technology and race-proven reliability to every ride, whether you´re sprinting on the flats or conquering the steepest mountain passes.Experience unparalleled shifting precision with Campagnolo´s innovative 3D EMBRACE TECHNOLOGY. This advanced system is engineered to mechanically optimize the derailleur´s trajectory. On the smaller sprockets, the chain is engaged with more teeth, which enhances power transfer, reduces wear on the drivetrain, and ensures perfect chain retention for ultimate security, even on rougher road surfaces. This technology ensures the upper pulley wheel remains at the ideal distance from every sprocket in the cassette, guaranteeing lightning-fast, accurate, and incredibly smooth gear changes across the entire 12-speed range.Designed for the modern road cyclist, the Chorus rear derailleur boasts incredible versatility. The single, medium cage design has been optimized to work perfectly with all compatible cassette options, including 11-29, 11-32, and 11-34 tooth combinations. This universal compatibility means you can easily adapt your gearing for any terrain without needing to change your derailleur, providing a simple and effective solution for all your road cycling adventures. The total capacity of 34 teeth gives you the freedom to tackle any gradient with confidence.Constructed with a meticulous blend of advanced materials, this derailleur strikes the perfect balance between strength, stiffness, and low weight. The outer plate is crafted from unidirectional carbon fiber, contributing to its low weight and providing the rigidity needed for crisp, decisive shifting under load. The upper body is formed from an ultra-light technopolymer reinforced with carbon fiber, further reducing weight without compromising durability. This focus on lightweight performance translates to faster acceleration and more responsive handling. Efficiency is further enhanced by the larger 12-tooth pulley wheels, which allow the chain to follow a smoother path, reducing friction and saving precious watts.Campagnolo Chorus Rear Derailleur.Key Features:* Flawless 12-Speed Shifting: Delivers rapid, precise, and reliable gear changes characteristic of the Campagnolo legacy.* Advanced 3D EMBRACE TECHNOLOGY: Maximizes chain engagement for superior power transfer, reduced wear, and enhanced chain security across all sprockets.* Universal Medium Cage Design: A single derailleur is compatible with 11-29, 11-32, and 11-34 cassettes, offering exceptional versatility for all types of road cycling.* Lightweight & Stiff Construction: Utilizes carbon fiber and...
