HOOK EXT FRAMESET
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.
