The new SRAM Rival DoubleTap shifters feature several substantial improvements. First, the brake lever is now made of carbon fiber to reduce weight and it is longer. One of the most beneficial improvements is the ability to trim the front derailleur along with faster Zero Loss front shifting. There are also more options for the cable routing as they can now be routed along either side of the handlebar. Finally, the reach is fully adjustable to allow riders to customize their position.
