The heart of this microSHIFT Acolyte derailleur is the innovative SpringLock system. By pairing a customized linear rate high tension spring and a dual stage activation mechanism, we’ve developed a system that can provide substantial chain security when you need it and can be turned off when you don’t.  To engage the clutch, turn the engagement bolt clockwise until it clicks. There’s no way to overtighten the bolt. To disengage the clutch for wheel removal, flip the switch. It’s that simple. - Innovative SpringLock chain retention keeps chain in place over rough terrain - Direct path cable routing for smooth and responsive shifting - Compatible with 12-42T and 12-46T 8-speed cassettes - Compatible with Acolyte shifters only

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
