The SRAM Force Rear Derailleur takes advantage of Exact Actuation™, an actuation ratio that delivers precise 3mm shifts in every gear along with the widest range of adjustment available, delivering the best 10 speed performance in the sport. The SRAM Force Rear Derailleur is crafted with cutting-edge materials, including a unidirectional carbon-fiber outer cage and a magnesium inner link, resulting in an impressively light 178g weight.
Carbon-fiber outer cage and magnesium inner link provide strength and light weight.
SRAM Force WiFLi Rear Derailleur (Medium Cage) lengthens it's cage and gets a slight variation in geometry to accomodate an 11-32 cassette. The range of gears is wider than a standard triple chainring system and saves a significant amount of weight.
