Shimano GRX RD-RX815 Rear Derailleur
Product Details
The Shimano GRX RD-RX815 Rear Derailleur is a component of Shimano's GRX groupset, which is designed specifically for gravel and adventure riding. The rear derailleur is designed to provide smooth and reliable shifting on rough terrain, making it ideal for off-road cycling.
The derailleur is compatible with Shimano's 11-speed drivetrains and is designed to work with cassettes with a maximum sprocket size of 34T. It features Shimano's Shadow RD+ technology, which provides a low-profile design that helps to protect the derailleur from damage and improves shifting performance.
The Shimano GRX RD-RX815 Rear Derailleur also features Shimano's clutch mechanism, which provides increased chain tension and helps to prevent chain drops, even when riding over rough terrain. This feature is particularly useful for off-road cycling, where the bike is often subjected to uneven terrain and obstacles.
The derailleur is available in both short cage and medium cage versions, which allows riders to choose the best fit for their particular drivetrain and riding style. The short cage version is designed for use with tighter gear ratios, while the medium cage version is designed for use with wider gear ratios.
