Overview
About this bike
The Ultimate Trail Bike The Mach 5.5 Carbon builds on the legacy of our renowned Mach 5.7 Carbon as the quintessential trail bike. With 140mm of dw-link rear travel, it sticks to and claws up just about anything, with unparalleled pedaling efficiency. On descents, the Mach 5.5 Carbon's incredible square edge bump performance and 160mm travel Fox 36 fork enable you to conquer terrain that makes other bikes cower. It's a bike that inspires you to climb while looking forward to the descents and that begs you to push your limits while putting a smile on your face. Ultra Light. Ultra Strong. Weight matters...and so does strength. The Mach 5.5 Carbon matches Mach 6 Carbon durability while achieving Mach 429 SL Carbon weights. The result is the perfect balance of frame stiffness and ride feel. The frame's carbon structure features our proprietary hollow core internal molding process combined with a highly optimized lay-up design, utilizing lighter weight, high modulus materials that save up to a pound (.45kg) over other trail and enduro bike designs. The Mach 5.5 Carbon is available as a complete bike, with builds weighing under 27lbs (12.2kg) complete with dropper, and with frame weights as low as 5.2lbs (2.35kg). Ultra Capable. The Mach 5.5 Carbon's well-balanced geometry makes it the ultimate trail bike weapon. We combined a long and low cockpit with a 66.5-degree head angle for high-speed stability and amazing downhill performance. The bike's short (430mm) chainstays and relatively steep seat angle help it rail the tightest corners and absolutely crush the steepest climbs. We've also evolved our mid-travel link design. By utilizing the same rear-shock pivot cartridge-bearing design found in our longer-travel models (such as the Firebird and Phoenix), we've given the Mach 5.5 Carbon the unmatched, small-bump compliance and traction that Pivot is known for—in a lighter weight and more compact design.
