Just sitting in your kitchen, the Hook EXT C screams fast. Whether you are gravel racing or bikepacking with your friends, you’ll be going ‘full-gas’ with a smile on your face.
New for 2024 is the T800 carbon frame, complete with optional internal cable routing and our signature collection of mounting points, for when you’re riding fast and light with only frame bags.

Upfront you’ll find the Seido’s MGV fork with its huge tyre clearance, internal cable routing and multiple mounting points for your kit. SRAM’s Rival 1x groupset provides braking and shifting duties via a 10 – 42T cassette, running with a 38T direct mount chainring on our Bombtrack Lyer crank.

The cockpit is from Seido, with the new Tackle handlebar and it’s 16° flare. All this is tied in with the multi-award winning Hunt 4Season Gravel hoops, sporting WTB 40 mm Venture tyres.
