The SRAM Force rear derailleur now features a unidirectional carbon cage and Red-inspired graphics. It features Exact Actuation for easy set up and precise shifts. Exact actuation means the derailleur moves 3mm for every shift over the entire cassette so even and exact shifts occur over entire shifting range. The Force rear derailleur has a very wide adjustment range so it can function with bent derailleur hangers and other issues. It is able to handle rear cassettes up to 28 teeth and standard or compact cranks.
