Three years ago Pivot unveiled their original 115mm trail and XC race machine, the Mach 4. A forward thinking bike for the time, it was the first di2 compatible mountain bike frame, with integrated internal wiring from the factory. This year’s model continues in the same mission, with largely the same geometry, but with small adjustments to the front triangle, a new rear triangle, boost, more heel clearance, and room for up to a 2.6-inch tire. We were able to meet up with the Pivot crew at the Park City press camp to see the new bike in person, and get out on the trails for a first ride impression.
The Mach 4 is now on its fifth generation, incorporating lessons learned along the way through the bike’s time racing in the XC circuit. Builds for the Mach 4 will be broken down into XC race and trail categories. The XC builds will be spec’d with a 100mm step cast Fox 32 fork, flat bar, carbon seat post, longer stem and will tip the scales in the 22 pound range. The trail category sees 130mm of front travel from a Fox 34 fork, as well as a dropper post, shorter stem, and riser bars. Out back, suspension duties are handled by a Fox DPS4 shock, which the Pivot crew says provides more bushing support and better handing from previous generations. The shock is also optimized for the DW link suspension and tuned to provide pro-level, World Cup quality, pedaling performance and the bottomless feel of a longer travel bike without sacrificing efficiency. The Float DPS shock features settings and a design that allows for an incredibly plush feel with a wide range of damping control while also offering an extremely positive “firm” position for fast climbs. When combined with the dw‐link’s patented position‐sensitive anti‐squat, the DPS4 shock gives riders even better traction on steep ups and over rough trail.
