Whether you're looking to add a hardtail to your quiver of bikes or are just getting introduced to the world of mountain biking, the Diamondback Mason Complete Mountain Bike makes a strong case for occupying that empty space in your garage. Not your typical short and steep hardtail, the Mason has always been a little more relaxed, with a slacker geometry and big, capable wheels that give it more confidence than its suspension would initially suggest. This year, Diamondback made the decision to adapt the Mason to 27. 5 wheels, adding front and rear Boost spacing to give the Mason better traction through challenging, rubbly trail conditions and a stiffer, burlier ride.

To keep you out on the trails and out of the shop, Diamondback spec'd the Mason's drivetrain with equal parts SRAM X5 and X7, double workhorse grou...
