The SRAM Force WiFLi rear derailleur can handle up to a 32t rear cog for those seeking a wide gearing range without the weight penalty, slow shifting and wide Q-factor of a triple crank. It features cutting edge material like a unidirectional carbon cage and magnesium inner link. SRAM's Exact Actuation provides 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 32 teeth and standard or compact cranks.
