SRAM Double Tap is an integrated gearshift and brake lever system designed by SRAM Corporation for racing bicycles.[1] It allows shifting gears without having to remove a hand from the bars, unlike previous down tube shifting systems. It was launched in late 2005 to compete with Shimano Total Integration and Campagnolo ErgoPower.[2] It is characterized by having a single shift lever per unit that the rider moves inward a short distance for upshifts and a longer distance for downshifts. It is lighter and smaller than competitors because it has few parts.[3]

In 2010 SRAM expanded the Double Tap technology from the original drop handlebars to flat handlebars on flat bar road bikes.[4]
