Summary

The Bombtrack Audax is celebrated for its luxurious ride quality and versatility, excelling in both comfort and performance across varied terrains. Its design caters to endurance riding with features like generous tyre clearances and bikepacking-ready touches, though some note its weight and mechanical brakes as drawbacks. The bike's ability to blend speed on tarmac with stability on rough surfaces makes it a standout in its category.

Pros
  • Luxurious ride quality

  • Versatile for all-road and bikepacking

  • Comfortable for long distances

  • Generous tyre clearances

  • Balanced geometry for confident handling

Cons
  • A bit weighty

  • Mechanical brakes lack power and modulation

  • Gearing can be a grind when climbing

Key Quotes
The Audax, however, makes a very compelling package, with its clearance for both large-volume supple tyres or knobblies, and a classy steel frame and an all-carbon fork with modern TA standards.

It is, however, an absolute blast to ride; I was truly surprised by how rapid it feels on tarmac.

Bombtrack's Audax is exactly what its name suggests: it's a mile-muncher that whisks you along in cosseting comfort.

A great bike for racking up the miles and enjoying the countryside but it could do with better brakes
