{{Short description|Gearshift system for bicycles}} thumb|right|SRAM Double Tap shifter and brake lever '''SRAM Double Tap''' is an integrated gearshift and brake lever system designed by SRAM Corporation for racing bicycles.<ref>{{cite web | url = http://www.bikeradar.com/gear/category/components/combined-brakeshift-levers/product/review-sram-force-doubletap-controls-27758/ | title = SRAM Force Double Tap shift/brake levers review | author = Gary Boulanger | date = 27 Nov 2007 | publisher = Bike Radar | accessdate = 2011-07-14}}</ref> 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.<ref>{{cite web | url = http://autobus.cyclingnews.com/tech/2005/shows/interbike05/?id=results/interbike0522 | title = SRAM steps up to the road with DoubleTap™ | publisher = Cycling News | date = September 26–30, 2005 | accessdate = 2011-07-14}}</ref> 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.<ref>{{cite web | title = Tech Talk: Mr. Zinn rides SRAM’s new road groups | url = http://velonews.competitor.com/2006/04/bikes-and-tech/tech-talk-mr-zinn-rides-srams-new-road-groups_9723 | author = Lennard Zinn | publisher = Velo News | date = Apr 10, 2006 | accessdate = 2011-07-14 | archive-date = 2012-07-06 | archive-url = https://web.archive.org/web/20120706003928/http://velonews.competitor.com/2006/04/bikes-and-tech/tech-talk-mr-zinn-rides-srams-new-road-groups_9723 | url-status = dead }}</ref>
