Shred everything on Diamondback’s Mason. This all-mountain hardtail rocks a lightweight aluminum frame and obstacle-toppling 29-inch wheels to charge up climbs, while its slack head angle, stout 142x12mm rear through-axle, and smooth 140mm-travel RockShox Sektor fork lets you descend like a pro. You’ll also love how the rugged, crisp-shifting 1x10 Race Face/SRAM drivetrain snaps through the gears, and how the Avid Elixir 1 brakes deliver all-conditions speed control. Outfitted with a host of Diamondback components, Kenda's awesome tires and an MRP chainguide to keep your chain locked on, you’ve got an outstanding package to rail technical trails all day.
