Overview
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.
Are you heading down the path least travelled? For a drop handlebar bike, the Hook EXT seldom faces terrain it cannot handle. A Columbus steel frame, a dedicated carbon fork and a sturdy 27.5’’ wheelset equip the EXT with an armoury to ride where other bikes would surely suffer. A Sram 1×11 Rival groupset suitably gives this machine the gears and brakes to match.
