The Fusion is the perfect blend of efficiency, capability, and reliability on the trail. The Fusion’s responsive handling characteristics and comfortable geometry will help you mix up your ride from the pathway, to the trail, and onto the singletrack.
The Fusion’s geometry has been optimized to provide you with the best possible experience when heading out for a ride. We’ve updated the geometry to reflect the needs of a true ”downcountry” rider, including 29” wheels, a low standover height, longer reach, and a slacker head tube angle. With features like 100 mm of front travel, internal cable routing, and a 1x drivetrain, the Fusion sits at the top as our best all-around hardtail.
