Catering to the demands of endurance riders and bikepackers, the 2021 Bombtrack Audax range is designed to be fast on smooth surfaces yet capable enough to handle rough roads all day long. Both build options come complete with high-volume WTB Horizon tires, loads of mounting options, as well as clutch derailleurs and thru-axles for even better performance on chunky roads. Find details on the 2021 Audax and Audax AL below.

2021 Bombtrack Audax

2021 Bombtrack Audax

The 2021 Audax is built up around a Columbus Chromoly steel frame, carbon fork, and a 2×11 Shimano 105 drivetrain. The frame and fork get rack and fender mounts, multiple bottle mounts, top tube bosses, and routing and mounting options for dynamo-powered lights, making it look pretty dialled for multi-day bike trips. The Audax has clearance for 650B x 47mm / 700C x 35mm tires, and is offered in a single Glossy Sage Green paint job. Watch the launch video below, followed by the complete build kit.

2021 Bombtrack Audax AL

2021 Bombtrack Audax AL

The 2021 Audax AL features many of the same specs as the steel model, but is built up around a lightweight aluminum frame, carbon fork, and a Microshift XLE 1×11 drivetrain. A few other subtle differences between the two are additional mounts under the downtube, clearance for 650B x 50mm / 700C x 35mm tires, and a dropped drive-side chain stay. Otherwise, the Audax AL comes with tubeless ready WTB Horizon 650B x 47mm tires, TRP Spyre mechanical brakes, and is offered with a Glossy Sky Blue paint job.
