As expected, SRAM has carried over some of the features of its MTB rear derailleurs to the road versions. The new derailleurs use what SRAM calls Exact Actuation cable pull ratio. This requires more cable movement than competing systems in order to actuate a shift, but not as much as on SRAM's mountain systems, resulting in a more robust setup that should be more tolerant of cable friction or slight misadjustment. While this bodes well for long-term and all-weather performance, it does, however, mean that SRAM's new rear derailleurs will not be compatible with either Shimano or Campagnolo levers. The top level Force rear changer will include a carbon fiber pulley cage and magnesium inner parallelogram plate that reduces the weight to only 174g. Rival will use a more conventional aluminum pulley cage and inner link but still will only tip the scales at just 190g. Both rear derailleurs will handle up to a 27-teeth rear cog.
SRAM has wisely designed the new Force and Rival front derailleurs to be fully compatible with either standard or compact chainrings, the latter of which is becoming increasingly common. A proprietary cable pull ratio is also used here as well (again, signaling a lack of compatibility with existing components) and both front derailleurs will be available in braze-on style with additional clamps required for band-type mounting. Both Force and Rival front derailleurs use a steel cage and aluminum construction for weights of 88g in braze-on version, and 102-103g for the clamp version.
