The microSHIFT Sword rear derailleur for 1x system features a modern and innovative design with elegant mechanical operation. The cage is designed to use with a single chainring and an 11-48t cassette, giving you a wide range and excellent climbing gears. Not only that, but the cage itself is replaceable, so you can repair a damaged cage or even switch to the 2x cage easily. It also features a hidden clutch design with instant engagement and silent operation to keep the chain secure over rough terrain. With the introduction of Igus bushings on the parallelogram, lateral stiffness and longevity are both improved, making shifting snappier and more robust. Even the barrel adjuster is innovative, with an orbital housing stop that rotates by 15 degrees to reduce cable friction from tight housing bends. - Compatible with Sword and Advent X shifters - Compatible with standard 10-speed chains - Silent clutch with instant engagement and integrated switch - Igus bushings for added stiffness - Replaceable cage - Max cassette range of 48t - Orbital barrel adjuster reduces housing bends for less cable friction
