DESCRIPTION
The Bombtrack Audax Steel is the premium Audax, built from Columbus Cromor double-butted tubing for that classic slim-tubed steel look with thoroughly modern details. A tapered head tube, T47 bottom bracket, 12mm thru-axles and a rear light mount sit alongside a Shimano GRX 600 2x11 groupset for crisp shifting and strong hydraulic braking. Luxurious 650B x 47mm WTB tyres and Ritchey finishing kit make it a supremely comfortable all-day adventure bike.

Who Is the Bombtrack Audax Steel For?
For the rider who wants the ride quality of fine steel with the versatility of a modern gravel bike. The 2x GRX drivetrain gives a wide, closely-spaced gear range for everything from fast group rides to loaded touring, and the hydraulic brakes add confident all-weather control.
In New Zealand, the Cromor frame and 47mm tubeless tyres deliver a smooth, planted ride across chip-seal, gravel and rail trails, while the rack, fender and light mounts make it ready for commuting and multi-day adventures. It is a bike built to be lived with for years.
