The EXT-C has 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.


The Hook EXT C comes complete with a carbon frame and V2 carbon fork with triple cage mounts for speedier off-road raids. Sram provide the bike’s 10 – 42T XD cassette for a great range of gears, so you can keep the pace high over whichever surface you decide to tear across.

Hunt handle the hoops, providing the bike with a tubeless-ready Adventure Sport 27.5’’ wheelset. Finished with head-turning tan-wall WTB Venture tyres, onlookers will have to be quick if they want to catch a glimpse as you fly through the undergrowth. It comes in this year’s glossy metallic black colourway, too.


The bike is constructed with a Toray T800 carbon blend frame, offering a lightweight and robust design, complete with through-axle compatibility, and mounts for racks and fenders.

It features an 85.5 mm T47 bottom bracket shell, a universal derailleur hanger (UDH), and options for fully internal cable routing, including internal routing for a hub dynamo.

Its Seido MGV full carbon fork complements the frame with through-axle support, mounts for fenders and triple cages, compatibility with 180 mm rotors, and suitability for lowrider racks. Like the frame, it also includes internal routing for a hub dynamo.

Gear shifting is managed by Sram Rival 1 double tap hydraulic levers, facilitating a 1 x 11 drivetrain with seamless transitions.

Braking is provided by Sram Rival flat mount hydraulic disc brakes, ensuring reliable stopping power under various conditions.
