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.
