SRAM Double Tap is an integrated
gearshift and
brake lever system designed by
SRAM Corporation for
racing bicycles. 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. 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.
