Bombtrack Audax

The Bombtrack Audax is a true all-road bike that refuses to be bound by convention, and lays claim to be one of the most versatile “back road” bikes on the market, switching back and forth from pavement to dirt and gravel without missing a beat. A robust, refined and adaptable Columbus Cromor frame is the starting point. With through-axles and a wide threaded bottom bracket, it should survive a lifetime of intense use, as will its lightweight full carbon adventure fork.

With all the fixing you need to secure your gear, the versatile Audax frameset offers a choice of 650B wheels with large volume tyres or 700C wheels with large road-orientated tyres.  The voluminous size of 650Bs keeps rolling resistance low, yet allows the Audax to swoop across a range of surfaces from paved roads to gravel tracks. While the 700C option offers an extra responsive and ultra smooth ride over less aggressive surfaces.

“If you’re in the market for a bike primed for bikepacking and gravel riding, you’d be forgiven for thinking Bombtrack’s Audax range doesn’t tick the relevant boxes. But don’t be misled by the name, which suggests long distance, road-based randonneuring… because these bikes can do a whole lot more than that” Bikepacking.com

Available either as a Bombtrack factory built bike with Shimano 105/Ultegra groupset and tubeless ready Hunt Adventure Sport 27.5’’ wheels, or as a frameset for building up with groupset, finishing kit and wheels of your choice (see below).

The Bombtrack Audax frame is built from premium Columbus Cromor tubing, with a tapered head tube, through axles, and rack and fender mounts.  For long distance riding, steel is arguably the best material for the job. Its natural resonance dampens road buzz and produces a ride so compliant that it’s more akin to floating than rolling. Complete with triple cage mount on down tube for optimized bottle position, bottle cage mounts underneath the down tube and on the seat tube, and full carbon fork with bottle cage mounts.

“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. With its wide gear range and small jumps between them – compared to a 1x drivetrain, at least – the Audax is an all-road bike that can do a whole lot more.”  BIKEPACKING.COM

As well as the standard Bombtrack factory-built full bike, we are also able to offer a full custom specification with the Audax; starting with a bare frameset we can build you a full bike using components of your choice (see below for some examples).
