BOMBTRACK AUDAX

Bombtrack Audax

The Bombtrack Audax is possibly the most versatile and supremely capable all-road bike that would can find – it refuses to be bound by convention, and is perfectly at home 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.  Subtle tweaks like the inclusion of an integrated rear light mount and internal cabling for 2021 help keep it bang up to date.

With all the fixing you could need to secure your gear, the Audax frameset can be built up with a choice of 650B wheels with large volume tyres or 700C wheels with (still 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 or as a frameset for building up with groupset, finishing kit and wheels of your choice (see below for some examples).

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
