Overview
About this bike
When the original Mason debuted, it blew minds — here was a 29er hardtail that could be ridden aggressively on the kind of trails you thought required a full-suspension bike. Adding plus-size 27.5×2.8" tires to the Mason was, in retrospect, a no-brainer. The Mason is still a brawler, but now it practically floats over the rough stuff, while retaining all the fun-loving traits that made it so popular. The Mason 2+ features a double-butted frame, crafted from weapons-grade 6061-T6 aluminum. Diamondback hung all manner of rowdy-ready parts on that rugged frame, including a RockShox Judy Gold RL fork with Boost 110 thru-axle, an accurate and robust SRAM NX single ring drivetrain, and SRAM Level T hydraulic disc brakes. The bike rolls atop Blanchard 38R wheels shod with the plus-size version of gravity-loving Maxxis Minion DHF and DHR tires. Ready to go anywhere? The Mason is the bike for you.
