BOMBTRACK HOOK EXT C 2024
The all-new Hook EXT C screams speed! Whether you are gravel racing or bikepacking with your friends, you’ll be going ‘full-chat’ with a smile on your face.
For the 2024 model we see the introduction of 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 tied in with multi-award winning Hunt 4Season Gravel hoops, sporting WTB 40 mm Venture tyres.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore Bombtrack cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local Bombtrack dealer or a professional bike fitter and have them determine the needed size.
