Overview
About this bike
As one of the first slack 29er hardtails, Diamondback's original Mason showed everyone how fun big wheels could be. Far from a boring to;wagon wheeler,to; the Mason piled up accolades, combining the speed of a larger wheel with a nimble platform. In keeping with its trailblazing spirit, the Mason proved to be the perfect candidate for 27.5to; Plus wheels. Redesigned around “mid-fat” wheels but made to keep the ride characteristics similar to a standard 27.5to;, the butted/formed aluminum frame is low-slung and slack, with a 120mm RockShox air fork. The ride has stayed distinctly all-mountain, benefiting from the increase in traction from running a 2.8to;-wide tire. SRAM Level hydraulic brakes, a wide-range NX 1×11 drivetrain, and wide bars have the Mason leading the way again.
