MICROSHIFT Advent rear derailleur 9s

Microshift Advent rear derailleur, 9 speeds, robust, with chain stabilizer (clutch), well suited for a 1 x 9 speed transmission. The super short cage version has a cage small enough to fit on a bike with 20″ wheels. The ratchet clutch and return spring tension have been finely tuned to compensate for the smaller cage and lighter chain, allowing the derailleur to provide quick, precise and smooth shifts. The all-metal body resists impacts and provides additional rigidity.
