The GX Eagle Single Click Shifter is specifically designed for the demands of E-MTBs. To prevent chain breaks and premature chain wear, the lever is engineered to allow only one gear change at a time. The MatchMaker X clamp is more than just a clamp; it accommodates up to three controls, allowing you to attach your XLoc suspension lockout, Sram shifters, and Avid brake levers, as well as your Reverb XLoc remote, all using just two clamps. ZeroLoss means "zero loss." When you operate the shifter to change gears up or down, the cable is immediately released, ensuring zero movement loss. There are no delays while you wait for the gear to engage. The gear is changed promptly and accurately. The X-Actuation technology, specifically developed for Sram 1x, ensures precise and consistent shifting across the entire cassette.
