The 2022 Pivot Mach 4 SL GX/X01 is a cross-country race machine that doesn’t shy away from big days and technical terrain. Built around Pivot’s ultra-light, full-carbon frame with DW-Link suspension, the Mach 4 SL feels razor-sharp on climbs and surprisingly composed on fast, chattery descents. With 100mm of rear travel and a 120mm fork up front, it strikes that modern XC balance — quick and efficient, but still forgiving enough to handle more aggressive lines. The mixed SRAM GX and X01 drivetrain provides crisp shifting without tipping into full top-shelf pricing, while the bike’s agile geometry keeps it lively and precise in tight singletrack. At its core, the Mach 4 SL GX/X01 is built for riders who want to line up at the start line one weekend and chase big mountain loops the next, all without sacrificing speed or control.
