Bombtrack Audax 650b All Road Frameset 2020

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.
