the Hook EXT

...takes 'road-plus' further off the beaten track and sets the benchmark for a steel gravel bike.

"CX/gravel geometry with clearance for bigger knobby mountain bike tires, something gravel racers have long dreamed of."

Introducing the Hook EXT

The Hook goes hooligan. Using the same Columbus tubing and carbon fork as the standard model, its tough and agile 650B wheels free up space for bigger tyres. Giving the Hook EXT the ability to smash its way through trails that would stall most other drop handlebar bikes, it's an unstoppable combo.

Highlights

  • Full carbon tapered fork with internal light cable routing, through axles and triple cage mounts. 
  •  
  • Columbus Cromor frame with tapered head tube, through axles, rack and fender mounts and T47 bottom bracket. 
  •  
  • New rear dropout. Same hanger as on the Beyond+. 
  •  
  • Top tube bag direct mounts, triple cage mount on  down tube and seat tube for optimized bottle position, bottle cage mounts underneath the  down tube.
