The Bombtrack Audax combines performance components with the solid reliability required for endurance riding.

The steel Audax bike that refuses to be bound by convention. A robust and adaptable Columbus Cromor frame is the starting point. With thru axles and a threaded T47 bottom bracket, it should survive a lifetime of use, as will it’s lightweight full carbon fork. With all the fixing points you need to secure all your gear, it’s 650b whels may once have seemed radical but are now widely accepted. Their voluminous size keeps rolling resistance low yet allows the bike to conquer a range of surfaces. Fitted with a mix of Shimano Ultegra and 105 parts along with Hunt Adventure Sport wheels.
