We built our reputation on the Mach 4; it is simply the most efficient, best climbing, sprinting and descending World Cup level cross country and endurance race bike ever built.
Off the chart frame stiffness, ultra-light weight, and awesome climbing traction come together to deliver an incredible race bike. But the beauty of the Mach 4 is that it descends like no other, putting its XC competition off the back.  More than one editor has stated that the Mach 4 descends as well or better than many longer travel bikes, yet possesses the refined handling and pedaling efficiency of an elite cross country race rig.

The Mach 4 is the tool of choice for elite level racers around the world - having won the 2010 24hr World Championships and countless other events. MTBR.com has named the Mach 4 the best XC full suspension bike for two years in a row and it’s not hard to see why. With superior pedaling performance, lighter weight and unrivaled stiffness, the Mach 4 is designed with one thing in mind: going fast! If your rides include a finish line, you’ll finish faster on a Mach 4.
