Bombtrack Hook EXT Frameset


SKU: BOMHXFR Categories: , Tag:

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.


The Hook’s hoodlum tendencies given free rein. Using a Columbus steel frame, dedicated carbon fork, and lively 27.5-inch wheels, the EXT can batter through territory out-of-bounds to other drop handlebar bikes.

As capable on backcountry campouts as it is on post-work blasts, the Hook EXT remains the choice when you’re unsure of the terrain, but know you want to have fun riding it.
