The Bombtrack Audax is one of the nicest looking, true gravel frames out there. Super crisp and handles like a dream. Slightly shorter rear end than the Hook Ext but is still a comfortable ride loaded up with bags for those long bike packing weekends. Also double up as a go to road bike, if you still like to run the old 700c wheels. Best set up with 650b WTB horizon tyres to smash road rides and that hard packed UK Gravel….
A steel Audax bike that refuses to be bound by convention. A robust and adaptable Columbus Cromor frame is the starting point. With through-axles and a threaded T47 bottom bracket, it should survive a lifetime of intense use, as will its lightweight full carbon fork. With all the fixing you need to secure your gear, its 650B wheels might once have seemed radical, but are now widely accepted. Their voluminous size keeps rolling resistance low, yet allows the Audax to swoop across a range of surfaces.
