The Force AXS derailleur is lighter, faster, and more powerful than ever before, all with style. With the capacity for cassettes ranging from 10-28 teeth to 10-36 teeth, this wireless marvel features a new, even lighter derailleur cage and a larger jockey wheel for increased drivetrain efficiency. It's a derailleur for both 1x and 2x setups, designed for the steepest climbs and descents, and is also 12 grams lighter than the previous generation of Force.
