Bombtrack Hook EXT - 2024

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 1x11 Rival groupset suitably gives this machine the gears and brakes to match.
