Diamondback Mason Bike 2017
Slack. Big wheels. Reborn.
"New" is such an overused term. Still, there's the Diamondback Mason Bike, and you've got to use the word. For one, this edition of the bike is rolling on 27.5+ wheels, and uses Boost, which is no longer emerging. It's here. So on the one hand, you can say that the Mason has the same stance it's always had. But in reality, you've now got the massively better traction afforded by a 27.5+ setup, and the stiffness provided by Boost. Grip, and no flop. It's a win- win.
Elsewhere, you'll find the other reasons you've loved the Mason all this time. It's built upon a low-slung and slack butted and hydroformed frame, with a 120mm Sektor RL 27.5+ fork. Shifting comes through SRAM NX 1x11 speed components, and the power via SRAM NX cranks with a 28T chainring. Brakes are SRAM Level hydraulic with 180mm rotors front and back, and the wheelset used tubeless compatible DB Blanchard 38 rims tied to Boost hubs on both ends, Thru Axle 15x110mm front, 148x12mm rear. DB comes through with most of the remaining cockpit components, including their DB35, 760mm wide alloy handlebar.
If you were a Mason fan before, you might have seen this one coming. The bike always had the tight rear end that favored a big wheel setup like this, and the Boost 27.5+ configuration Diamondback chose this time around makes it feel like this bike is on the right path.
- Low-slung geometry, wide bars, and a 120mm travel fork all the ingredients needed to Rev it up
- SRAM NX 1x11 Drivetrain Reliable, economical, no non-sense, get the job done type of components.
- Tubeless-compatible wheelset Schwalbe Nobby Nic tires can do that
- Increased traction and wheel stiffness thanks to BOOST
