Designed to optimize the performance of Shimano´s latest generation of mountain bike transmissions, these jockey wheels reduce friction, improve shifting accuracy, and add a touch of personalized style to your bike.Experience a noticeably smoother and quieter ride. The oversized design of our jockey wheels decreases the chain´s articulation angle as it runs through the rear derailleur, resulting in significantly lower friction and increased drivetrain efficiency. This means more of your power is transferred directly to the rear wheel, saving you precious watts on climbs and sprints. The unique tooth profile of each pulley is specifically engineered for its role: the upper pulley ensures crisp and immediate gear changes, while the lower narrow-wide pulley provides superior chain retention, giving you confidence even on the roughest trails.Key Benefits:* Enhanced Shifting Precision: Enjoy faster, more accurate, and reliable shifting thanks to the specially designed tooth profiles that guide the chain flawlessly across your cassette.* Increased Drivetrain Efficiency: The oversized pulley wheel design reduces chain friction, leading to a smoother pedaling feel and measurable power savings, allowing you to ride faster and for longer.* Unmatched Smoothness and Longevity: Equipped with high-quality, sealed bearings , these pulleys spin with minimal resistance and are built to withstand the harshest riding conditions, from mud and dust to high-pressure washing.Main Features:Our Shimano 12-speed jockey wheels are crafted with performance at their core. The oversized pulley configuration is a key feature, providing a tangible improvement in drivetrain performance. We have developed a specific tooth shape for each pulley to optimize its function within the transmission system.
