Diamondback Mason 1

Rip the trail less traveled on the Mason 1, a hard-charging 27.5+ hardtail.

The Mason 1 is a hard-charging trail bike that plows through the rough stuff, yet remains fun and flickable. Plus-size tires add insane levels of traction and control without adding the weight of a rear suspension system. This hardtail gets the job done with sturdy double-wall wheels wrapped with 27.5x3.0-inch tires. An SR Suntour XCR 34 fork provides 120mm of travel to get you through the rough stuff, while Tektro Aries mechanical disc brakes keep your speed under control. The 1x10 Shimano drivetrain makes shifting simple, meaning no pesky front derailleur to fiddle with while you monster-truck over rocks and roots. Take the trail less traveled? Sure. And with the Mason 1 you’ll be ripping the trail less traveled.
