Description

Mach 5.5 Carbon Mountain Bike Frame

As Pivot's quintessential trail bike, the Mach 5.5 Carbon Mountain Bike Frame represents everything you need in a modern mountain bike. You'll enjoy progressive geometry that's longer, slacker, and lower for unflappable composure at high speeds over aggressive terrain. You'll also reap the rewards of 5.5-inches of buttery smooth and strikingly efficient DW-Link suspension travel that keeps your tires glued to the ground as you crest technical climbs, plow through chunky rock gardens, and rocket down blistering descents. And being a Pivot, the carbon fiber frame is exceptionally well-made, offering impressive strength at a very competitive weight. In short, the Mach 5.5 is an ideal trail bike for riders that demand the very best from their equipment. Riders who need a bike that climbs like a goat and descends like an enduro race sled, but is quick and agile in order to keep the fun factor high on flowy singletrack.

The Mach 5.5 Carbon retains the sought-after benefits of the DW-Link suspension platform, namely the ability to claw up the steepest, chunkiest climbs and soak up square-edge hits on the descent, all while staying active under braking. Once you've reached the summit after a grueling climb, 5.5-inches of rear travel gobbles up loose rocks and smooths out choppy terrain at high speeds. It's all party up front, with 6.3-inches of fork travel providing the confidence to rally across anything in sight, including sections usually reserved for longer-travel rigs. This 20-millimeter disparity between front and rear travel gives you a bit more efficiency for pedaling, but with extra plushness up front for cleaning notoriously technical sections of trail.

Seeing the industry is constantly evolving, it makes perfect sense to see the Mach 5.5 Carbon with a slacker, longer, and lower geometry for riders seeking a progressive trail bike that stays glued to the trail and retains stability at high speeds. The 66.5-degree head tube angle offers composure on high-speed descents, without being overly slack or wandering excessively on sustained climbs with steep, punchy sections. Just a tick shorter in the front than the notoriously long and slack Firebird, the Mach 5.5 Carbon's long top tube gives you ample cockpit room, which is especially welcome if you have a longer reach. This longer front end is complemented with snappy-short 16.93-inch chainstays. Shorter chainstays provide greater maneuverability for cleaning tight corners and uphill sections, as well as lifting the front up and over trail obstacles.

A few key details make the Mach 5.5 Carbon a truly stand-out trail bike. Delving into its carbon frame construction, Pivot employs their proprietary hollow core internal molding process with an optimized lay-up of high-modulus carbon for the lightest weight possible without sacrificing strength. This method produces a feathery-light frame (claimed as low as 5.7lb) that approaches Mach 429 SL Carbon territory, but with strength and stiffness similar to the enduro-bred Mach 6. In the rear triangle, both the seat and chainstays clear tires of 2.6 inches, which is a nice benefit for riders seeking the added bump compliance and cornering grip of high volume trail tires. Lastly, every frame size has enough room for a large water bottle in the front triangle, and there's even a second water bottle mount under the downtube on small through extra large frame sizes.
