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.
- Ultra-light weight: At only 5lbs, the Mach 4 frame is one of the lightest XC Full Suspension frames in the world while also being the stiffest XC bike made. A complete XX equipped bike weighs only 21.8lbs while race team bikes are being built up under 20lbs. (9kg).
- dw-link® suspension design with position-sensitive anti-squat makes for the most efficient pedaling and best performing race bike on the market.
- New Fox Adaptive Logic RP23 Kashima shock with custom tuned rebound and Propedal settings: this new configuration allows racers quick access to the full maximum Propedal setting while still being able to select the other settings based on the course or riding conditions.
- 100mm (4") rear travel with 100mm or 120mm fork compatibility.
- Tapered 1.5" headtube for increased front end stiffness and control.
- Press Fit 92mm wide bottom bracket, direct mount front derailleur, double row bearing carbon dw-link®, and high-modulus carbon rocker add to the Mach 4's superior frame stiffness and incredible long-term durability.
