HOOK EXT RIVAL AXS
Steel is real. Especially when the Hook EXT Rival AXS comes equipped as standard with Sram’s electronic Rival AXS 1x12 groupset and hydraulic brakes. The drivetrain comes finished with the Sram Rival Wide 38T direct mount chainring for consistent chain control. The Columbus Cromor double-butted frame with tapered head tube and rear light mount will last longer than the test of time. So you can hit the road less travelled, wider rims improve tyre performance. You’ll also have more mounting options than to shake a fist at: top tube direct mounts, triple cage mounts on the down tube and seat tube for cargo positions of your choice, as well as underneath the down tube and rear rack mounts for those adventures that delve deep into unknown territory.
The Hook EXT is the choice when you're unsure of the terrain, or know you want to cut loose.

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.
