2019 Pivot Mach 4 Carbon Race X01 27.5″


The Mach 4 Carbon is the ultimate lightweight, flickable trail bike. Let’s start with the weight—or lack of it. The Mach 4 Carbon’s frame weighs a mere 5.1 pounds (2.3kg). Complete bikes tip the scales at less than 22 pounds (10kg). In other words, it’s a featherweight; it got that way thanks to both our proprietary hollow-core, internal molding process and a combination of highly optimized layup structures, tube sections, and material choices.

At Pivot, however, we don’t believe that “lightweight” should ever equal “flexy”. That’s why the new Mach 4 Carbon features a fully redesigned rear triangle that boosts stiffness and tire clearance. The confident handling of the Mach 4 Carbon also gets a boost from its mid-sized 27.5” wheels and flex-fighting Boost 148 rear hub spacing.
