The Apex shifter utilises a single lever for shifting & a dedicated lever for braking. It also features a shift lever that is both close to the bar as well as tailored to an optimised 15 degree sweep to provide the rider with superior control in all situations. All of these mechanical features are packaged in an exceptionally light 344g package, & features no external cables to maximize aerodynamics. New SRAM&174; Apex is the perfect blend of technology & performance, so all riders can challenge their personal limits. SRAM&174; Apex has double chainrings, which are simpler, lighter, faster, & in every way, just better than a triple. & with a gear range thats wider, making climbing easier & descending faster, why would you ever go back to three?
