In the considerable undertaking that was creating a 12-speed drivetrain, every piece of componentry received a laser focused attention to detail and engineering ingenuity. With the XX1 Eagle 12-Speed Trigger Shifter, SRAM introduces a well-executed carbon and aluminum design that builds on its 11-speed predecessors to stand on its own and allows you to get the most out of your XX1 Eagle drivetrain.In addition to its ability to shift through a massive range of 12 gears, the XX1 Eagle Trigger Shifter comes with a brand new internal shifting mechanism that improves responsiveness and smooths out shifts compared to older XX1 shifters. It includes SRAM's Zero Loss technology as well, ensuring you don't experience lag time when you throw the lever heading into a big climb or punching out of a switchback. The updated internals boast improved longevity, as well as the customizable capability to upshift by up to five gears at a time. This shifter also comes with SRAM's Matchmaker compatibility, allowing it to integrate cleanly with the rest of your cockpit and keep the shifter, as well as various suspension and dropper post remotes, arranged in one easy-to-access place on the bars.
