Information

2013 Diamondback Assault Dirt Jump Bike

The Assault features a 6061-T6 Aluminum frame with Tapered head tube, Mission formed top tube and steel reinforced horizontal BMX dropouts, these frames are stout and fully capable of going big. And weighing in at a respectable 4.5 lbs makes this one of the lighter dirt jump frames on the market. Designed and refined through feedback from Diamondback riders, the Assault is a burly little low slung rig designed to trick, flip, stick and hit.

A single speed specific horizontal dropout keeps things clean and simple. 69° head and 72° seat angles combined with significantly compact 15.3" chain stays and a 22" sloping top tube make the Assaults easy to throw around and manual. The Assault comes spec'd with a Fox 32 "831" CTD "FIT" fork. The fork has100mm of travel, a 15mm quick release thru axle and is internally adjustable to 110mm or 120mm. This keeps the front end snappy and agile. Tubular chromoly cranks provide a solid jumping platform while the Alienation wheel set provides stout landing gear. A single rear Shimano M505 hydraulic disc brake with a 6-bolt XT SM-RT76 160mm rotor provide ample stopping power. A Gravity Light stem, 800mm bars and a Diamondback signature Pivotal seat and Alienation Billy Club post are included.
