SRAM Apex® DoubleTap® Controls
The new Apex Shifter, like every SRAM road group, features the proprietary DoubleTap® technology, which offers benefits such as independent reach adjust for both shift and brake levers. The Apex shift lever utilizes a single lever for shifting and a dedicated lever for braking. All of these mechanical features are packaged in an exceptionally light 344g package, and features no external cables to maximize aerodynamics and provide a sleek look.
- Proprietary DoubleTap® technology delivers smooth up- and down shifts in one motion
- Ergonomic design is comfortable, aerodynamic, and hides all cables, while weighing only 344g
- High pivot brake lever with reach adjust

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.
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. 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.
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.
