Mach 4 SL Frame with Fox Factory Float shock and 100mm dw-link travel
What Our Gearhead® Experts Are Saying:
"I appreciate that this frame comes equipped with a Fox Factory Float shock because it saves time dialing in a high-end XC build. The dw-link platform feels firm under power but still active when the trail gets rough. It’s an ideal base for a lightweight race setup that blends efficiency with real trail capability."
The Mach 4 SL Frame pairs Pivot’s advanced hollow-core carbon construction with a Fox Factory Float rear shock to create a race-focused cross-country platform. Delivering 100mm of dw-link rear travel, the frame maximizes pedaling efficiency while maintaining traction and small-bump compliance for technical race courses. The included Factory-level shock ensures precise damping control and lightweight performance that aligns with competitive XC demands.
Boost 148 rear spacing enhances lateral stiffness and broadens modern wheel compatibility, while internal cable routing supports seamless integration of 1x drivetrains and dropper posts. Designed around a 100mm suspension fork, the geometry promotes sharp steering response and confident descending control.
Whether we are building a podium-ready race bike or a fast and efficient marathon machine, the Mach 4 SL Frame with Fox Factory Float shock delivers a refined, competition-driven foundation built for speed.
Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
