the Hook EXT-C

Matt Metallic Black

when you want to go wild places fast

"With the ability to carry serious loads, triple mounts on the forks and three separate bottle cage fixings allow you to carry as much as you need with you.”

Introducing the Hook EXT-C

When you want to go wild places fast. An ultralight carbon construction strips mass from the Hook EXT while retaining the versatility the range is known for. Backed by equally quick 650B Hunt Adventure Sport wheels and easy rolling WTB Ranger tyres, it’s the endpoint of our speed focused gravel line. With the ability to carry serious loads, triple mounts on the forks and three separate bottle cage fixings allow you to carry as much as you need with you. Building speed, or stopping everything in seconds, the entire package is backed up by Sram’s Rival gearing and brakes.

Highlights

  • Full carbon tapered fork with through axles and triple cage mounts. 
  •  
  • Full carbon frame with tapered head tube, through axles, rack and fender mounts, stealth dropper post routing and T47 bottom bracket. 
  •  
  • Hydraulic Sram Rival 1x11 groupset and brakes with wide range 11 - 42t cassette. 
  •  
  • Tubeless ready Hunt Adventure Sport 27.5’’ wheelset with tubeless ready WTB Venture 27.5’’ x 2.0’’ tires. 
  •  
  • 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. 

"With its chunky 650b tyres and light and stiff carbon frame, the Bombtrack is straying perilously close to a hardtail mountain bike, but there’s enough to distance it.

It’s smooth and swift on the road, and insanely good fun off the road in the trails and woods, with bags of enthusiasm and planted handling that will have you grinning from ear to ear."  (road.cc)
