Everything received the same detail, including the transition between handlebar and hoods, the grip texture, finger wrap, and the separate interfaces with both the shifter and brake lever. The understated black finish makes it look fast and a perfect match for any machine. DoubleTap What It Is: DoubleTap® is the flagship technology leading SRAM’s road gruppo revolution. It’s a simple yet elegant and advanced system that addresses issues – Without compromising on performance, comfort, and weight – with a revolutionary shift/brake lever design. What It Does: DoubleTap® makes changing gears easier and faster, eliminating the cumbersome and awkward engagement associated with two-lever systems. DoubleTap handles up- and downshifts in one short, sweeping motion, with minimal effort and maximum comfort no matter where you are on the bars. How It Works: DoubleTap® uses two pawls, one for holding the ratchet wheel, and one for transporting it up and down through the gear change. The pawls are arranged in a way so that they can leapfrog each other depending on how far, and with how much pressure, you push the shift lever. With short, rapid taps the transport pawl (04) moves the ratchet wheel (02) up through the shifting range. Downshifting comes via a longer sweep of the lever (in the same inward direction you upshift, but to an ergonomically maximized 15° angle) with the holding pawl (03) and the transport pawl leapfrogging each other quickly and smoothly. Location, Location, Location: DoubleTap’s one-motion unidirectional levers (05) work flawlessly no matter what position you’re shifting from. Its double-articulated design (01), which is completely separate from the brake pivot, is easily engaged from the hoods or the drops. Unlike all other forward controls, DoubleTap® also lets you pull the shift lever in against the bars so you can upshift while sprinting or attacking without giving up a firm grip. Divide and Conquer: On DoubleTap® controls, the brake and shift levers are completely independent, each operating with their own pivot points. This not only allows for the multiposition functionality, it also eliminates the risk of engaging brakes or shifters unintentionally – an unfortunate side effect of other shift/brake lever designs. What It Means To You: The efficient and ergonomic design reduces weight and eliminates bulk while adding comfort. You can shift from any position on the bars, even while sprinting, giving you a critical advantage over your competition, and our new single-lever mechanism also lets you shift faster, easier, and with more accuracy, without risk of scrubbing speed or losing your grip. DoubleTap® is the cornerstone of SRAM’s assault on road biking. It’s a new way of shifting – and a new way of thinking – that will put you ahead of the competition, no matter where you find it. ZeroLoss™ ZeroLoss simply means, well, zero loss-when you push on the lever, for an upshift or down shift, the cable is engaged instantly-zero loss of movement. There is no middle-ground where you’re waiting for the shift to come. Gear changes are instant and precise. ErgoDynamics™ It consists of three separate elements to significantly improve your riding experience on SRAM DoubleTap controls. The brake lever is slightly longer than previous DoubleTap road controls to enhance the reach from the drops. The independent reach adjust features on the brake and shift levers are easier to access to quickly adjust for every hand size. Finally, the shape of the hoods has been completely redesigned with a smaller diameter and higher top shape to increase the rider’s control and improve finger wrap.
