Pivot’s inaugural model was the Mach 4, a cross-country oriented 100-millimeter-travel dual suspension bike. Its aluminum chassis incorporated a number of innovations, like rockers and bottom bracket assemblies that were welded together from two halves to form lightweight hollow structures, and Pivot also was one of the first bike brands to commit to Dave Weagle’s anti-squat suspension technology. Much has changed since then, most notably the public’s perception of the basic cross-country trail bike. Unless one happens to be an XC racer, most trail riders are choosing suspension travel in the neighborhood of 120 to 140 millimeters, largely because there is little if any weight penalty for moving up to a more capable chassis, and also because suspension no longer is a pedaling efficiency issue. Pivot, however, believes that many hard-core riders and racers out there long for the snappy acceleration and razor-sharp handling that the Mach 4 was born to deliver, and that the role of the short-travel dual-suspension bike is more valid than ever, so much so that they threw every trick they knew into this week’s featured test bike: the Mach 4 Carbon.
