The all-new Mach 4 SL is designed to let World Cup level athletes capitalize on every inch of increasingly technical courses and generate speed where others hesitate. Our engineers have pushed the boundaries in every conceivable metric of cross country performance. It’s the lightest, fastest 100mm travel XC race bike we’ve ever developed. Go ahead, turn yourself inside out and leave it all out on the race course because the new Mach 4 SL leaves nothing on the table.
Cross country racers know that every gram counts. Pivot’s engineers didn’t set out to cut a few grams – they insisted on slashing hundreds. Starting at 1845 grams, the Mach 4 SL takes a front row seat in the ultralight full suspension category and has the best stiffness to weight ratios we've ever created. The new Mach 4SL is over 300 grams lighter than its feathery predecessor, the Mach 429 SL - that’s 3/4 of a pound! Optimized tube shapes, a more compact frame design, exotic hi-mod materials, and a dual upright, reinforced swingarm push strength and stiffness while allowing weight to be shaved everywhere. More weight evaporates with an integrated headset and race-proven carbon suspension bearing pockets that leave almost no metal in the frame. Steep climbs and sharp accelerations never felt so good – or fast.
