Overview
About this bike
Always at the top of the list for fun big-wheeled hardtails, Diamondback's Mason Pro takes another step forward with the ridiculous traction of 27.5 Plus wheels. The frame is ready for this new direction, keeping its short rear end and relaxed head angle. The bike keeps its formed/butted aluminum tubes and slack geometry, but gains even more confidence with a 130mm Fox 34 Float fork and the gigantic contact patches on those high volume tires grabbing traction on every conceivable surface. The component build is top notch too, with a 1×11 SRAM drivetrain, wide Diamondback Blanchard rims, and a KS dropper post standard. For riders who want to take their mountain biking further, the Mason Pro is the all-mountain hardtail.
