The SRAM Apex Shift & Brake Lever like every SRAM road group, features the proprietary Double Tap technology, which offers benefits such as independent ''reach adjust'' for both shift & brake levers. The Apex shift lever utilises a single lever for shifting & a dedicated lever for braking. All of these mechanical features are packaged in an exceptionally light 344g package, & features no external cables to maximize aerodynamics & provide a sleek look.
