Details

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.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore BOMBTRACK cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local BOMBTRACK dealer or a professional bike fitter and have them determine the needed size.
