2019 Pivot Mach 4 Carbon XC/Trail Special 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.

We are offering this Mach 4 Carbon with a special speedy XC Race build or versatile XC/Trail friendly build for just $3,999.

The mach 4 Carbon is one of the world’s fastest cross-country bikes and raced at the highest levels such as World Cups and the Rio Olympics. It also fits an incredibly wode range of rider heights from 4’10” to 6’2″ without compromise making it the perfect bike for youth and adult racers alike.

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.
