Pivot’s roster of world class downhill and enduro athletes had tons of input into the 155mm-travel Mach 6 Aluminum. The 27.5-inch wheels, slack head angle, short chainstays and low BB height all add up to an incredibly versatile and capable bike that proves aluminum isn't dead. Pivot worked for three years to develop a variable wall thickness hydroforming technology that allows them to create highly complex tube shapes that were previously only achievable in carbon. Pivot is obsessed with stiffness, they know it means the difference between winning and losing, holding your line or ending up spit out in the weeds. And they nailed their frame standards for stiffness, power transfer and perfectly dialed suspension performance, culminating in a bike that raises every rider’s ability to conquer aggressive, technical trails.
