The all-new Mach 4 SL is the lightest, fastest 100mm travel XC race bike Pivot has ever developed. 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 Pivot has 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.

Proper fit is critical to maximizing the body’s output, so Pivot 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 the 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.
