Nova Ride Shimano Ultegra/Dura-Ace 12s Pulley System

The Nova Ride Shimano Ultegra/Dura-Ace 12v Pulley System is designed to optimize drivetrain performance, offering a significant power gain. Here are the main features:

• Composition: The system consists of a lightweight carbon cage and two 7075 aluminum rollers with fully sealed ceramic bearings. These high-quality components are designed to reduce friction and improve transmission efficiency.

• Compatibility: This version of the Oversize cage is compatible exclusively with Shimano Ultegra R8100/Dura-Ace R9200 rear derailleurs. Please make sure your derailleur is the correct version before installing.

• Power Gain: The system offers an estimated power gain of between 4 and 5 watts compared to a conventional screed. This can help improve the overall performance of your bike.

• High-quality materials: The cage is made of ultra-light carbon fiber, ensuring strength and lightness. The oversized aluminum rollers, combined with ceramic bearings, reduce the chain's wrap angle, minimizing friction and improving transmission fluidity.

• Weight: The overall weight of the system is 68 g, contributing to the overall lightness of the bicycle.

• Color: The Nova Ride Pulley System is available in gold, adding a touch of style to your drivetrain.
