Bombtrack Hook Ext Gravel Bicycle | Matt Forest Green

By Bombtrack


Introducing the Hook EXT: The Hook goes hooligan. Using the same Columbus tubing and carbon fork as the standard model, its tough and agile 650B wheels free up space for bigger tyres. Giving the Hook EXT the ability to smash its way through trails that would stall most other drop handlebar bikes, it's an unstoppable combo. Gearing and brakes are taken care of by Sram’s 1x11 Rival groupset. Putting more air between you and the trial, the Hook EXT is the choice when you’re unsure of the terrain, or know you want to cut loose.
