Intro 

This version distils the EXT philosophy into something quiet but powerful: a bike that performs exceptionally without drawing attention to itself. The SRAM Apex Eagle 1×12 drivetrain delivers a wide, intuitive range for steep climbs, loaded touring and long mixed-terrain rides. With 27.5” wheels, traction and control are significantly improved on rough or loose surfaces.

If you want an adventure bike that prioritises substance over flair — and that feels composed, capable and confident across varied terrain — the Matt Black EXT is an excellent choice. We're always available to help you compare sizes or understand how it fits your riding style.

The Hook EXT Apex Eagle in Matt Black is the most understated and purposeful interpretation of the model. A clean, functional aesthetic that lets the bike disappear beneath you so you can focus entirely on the ride. The matte finish highlights the steel frame’s lines and conveys durability, precision and a tool-like sense of reliability.

Technical Interpretation

The Hook EXT 2025 supports advanced tyre configurations thanks to its asymmetric frame–fork clearances:

Key limits

  • Frame: 52 mm max in 27.5” • 40 mm in 700C
  • Fork: up to 57 mm in both formats

Advanced configurations unlocked

1) Mullet Width Setup

  • Wider front, narrower rear
  • More control, stability and grip on technical terrain
  • Ideal for roots, rough gravel and fast descents

2) Front Traction Bias

  • Wide front tyre → traction and confidence
  • Slightly narrower rear → faster rolling, zero frame rub
  • Perfect for technical bikepacking with varied surfaces

This asymmetrical clearance is one of the Hook EXT’s major advantages over many competing gravel bikes.

¹ Size recommendations generally represent 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. The best way to work out the correct size is to consult your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter and have them determine the needed size.
