Overview
About this bike
Gravity Defying Cross Country Rocket Ship The 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. Weighty Goals 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. Short or Tall, it Fits Them All Proper fit is critical to maximizing our body's output, so we made sure the Mach 4 SL fits the widest range of riders and all genders without compromise. The extra-small size fits riders down to 4'10" with a lower standover height than even our Mach 4 Carbon with 27.5" wheels, and the extra-large size fits riders up to 6'7" tall. A shorter stack, longer reach, and steeper seat angle put you in a powerful position to churn out the watts mile after mile. Size-specific carbon layups and shock tunes make sure all riders experience the same cutting edge performance and ride across the size range.
