This is one of the most sophisticated interpretations of the Hook EXT platform: electronic shifting, wide-tyre geometry, strong off-road character and the dependable ride feel of a Columbus steel frame. Whether used for gravel, mixed-surface adventures or bikepacking, the Hook EXT Rival AXS delivers confident handling and a smooth, composed ride. It is a gravel bike designed for riders who want both performance and style in equal measure.

700C × 57C

Technical Interpretation

The Hook EXT Rival AXS provides valuable flexibility thanks to the difference between frame and fork clearances:

  • The frame fits up to 52 mm tyres in 27.5" mode.
  • In 700C, the frame clearance is 40 mm.
  • The fork is significantly more permissive and accepts up to 57 mm.

This allows highly effective setups:

  • Mullet width: wider front tyre for greater traction and control on technical gravel.
  • Front traction bias (bikepacking-inspired): wide front tyre for stability, narrower rear tyre for efficiency and reduced frame rub – ideal for long mixed-terrain routes.

This adjustability is one of the Hook EXT’s strongest advantages in real-world use.

¹ The bike size recommendation is intended as a general guideline to quickly narrow down options based on rider height. Proper bike fitting is a complex topic and should also consider other body measurements and factors. Since no two riders are identical, it is not possible to guarantee that these recommendations will be correct for everyone. The best way to determine your ideal size is to consult your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter.
