Diamondback Mason 2 Mountain Bike (2019)


SKU 02-0210673

The Mason 2 is a hardtail that can be ridden aggressively on the kind of trails you might have thought require a full-suspension bike. This trail bike is a fun-loving brawler, yet it practically floats over the rough stuff thanks to its ultra-wide, plus-size 27.5×2.8-inch tires. Diamondback hung all manner of rowdy-ready parts on its rugged aluminum frame. The Mason 2 rolls atop Blanchard 38R tubeless ready wheels and comes equipped with a RockShox Judy Gold RL 120mm travel fork. A SRAM NX 1×11-speed drivetrain paired with Race Face cranks keeps you motoring uphill and down. Stay on your line thanks to the SRAM Level T hydraulic disc brakes. The Mason 2 is ready to rumble.


  • Light and strong aluminum frame with precision-enhancing 148x12 Boost dropouts and rear thru-axle 
  • RockShox Judy Gold RL eats up bumps with its 120mm of plush travel
  • Race Face cranks and SRAM NX 1x11 drivetrain makes for simple and efficient shifting
  • Plenty of stopping power, courtesy of SRAM Level T hydraulic disc brakes 
  • Diamondback’s Blanchard 38R wheels and Vee Rubber T-Fatty 2.8” tires offer insanely good grip
