Efficiency Engineered

Built with our highest-modulus carbon fiber, the Mach 4 SL sets a new standard for stiffness-to-weight ratio. A reimagined frame channels every watt into pure acceleration, while updated geometry places you in the optimal pedaling position and keeps handling precise and predictable at speed. On the trail, the Mach 4 SL’s dw-link suspension design delivers instant acceleration out of corners, unwavering traction on steep climbs and the momentum to stay ahead when the pace surges.

XC Evolved

XC courses have evolved, and the Mach 4 SL is evolving with them. A slacker head angle, 120mm fork and refined kinematics deliver composure when the trail gets rough while preserving the bike’s razor-sharp cornering precision. It’s stable when you’re dropping into technical descents yet agile enough to carve corners at race speed.

Refined for the Ride

Every detail serves the rider who demands focus at full gas. Discreet cable ports keep the cockpit clean and versatile, ready for anything from wireless droppers and shifting to full mechanical setups. Pivot’s Toolshed™ downtube storage integrates seamlessly, ensuring essentials are always there when you need them and never in the way. With adjustable travel options from 110 to 120mm, the Mach 4 SL is engineered for adaptability—ready for technical courses, all-day epics and everything in between.
