Introducing the Audax: A steel Audax bike that refuses to be bound by convention."

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. Fitted with a mix of Shimano Ultegra and 105 parts along with Hunt Adventure Sport wheels, this year sees the introduction of a new XS size.
