Pivot Cycles Mach 4 SL World Cup XX SL AXS Fox Live Valve (Carbon Wheels)

A gravity-defying cross-country rocket ship.

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.

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. A shorter stack, longer reach, and steeper seat angle put you in a powerful position to churn out the watts mile after mile.

Our Engineers Pushed the Boundaries
Optimized tube shapes, a more compact frame design, exotic hi-mod materials, and a dual upright, reinforced swingarm push strength and stiffness on this gravity-defying cross-country rocket ship.
