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.
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.
Features:
Wheels: Wide rims (i25 front / i23 rear) for improved tire performance
Frame: Columbus Cromor double butted frame with tapered head tube and rear light mount
Fork: Full carbon tapered fork with internal light cable routing, through axles and triple cage mounts
Hubs: Bombtrack Tau 12mm through axle hubs
Crank: Bombtrack Lyer 30mm aluminum crank with 40 T direct mount chainring
