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