Overview
About this bike
Reliable, affordable, and capable of nearly erasing roots and rocks. We love hardtails, but there's no denying the benefits of full-suspension mountain bikes—the added comfort and control. Unfortunately, dualies often add another thing: more dollar signs to the price tag. That's not the case here. The Atroz utilizes sealed cartridge bearings in an understated single-pivot design to deliver smooth, durable performance. The Atroz 2 ups the ante with Shimano hydraulic disc brakes, Suntour air-sprung rear suspension and an easy-to-operate single-ring drivetrain—features you usually find on bikes with a whole lot more dollar signs on their price tags.
