The Audax, with its slender steel frame, light carbon fork, and many mounts for luggage, will let you take long-distance riding to the limit. As the miles roll by, hydraulic disc brakes provide reliable stopping power while a sub-compact drivetrain handles propulsion. A combination of WTB Horizon and Byway tires are fast-rolling over gravel, mud, or dirt. The integrated rear light mount brings the discipline into the modern age. Topped off with Ritchey finishing kit, you’ll reach the coast before this bike gives up.

Fast on tarmac, smooth over broken ground, its broad tires contain enough air to carry you and your kit comfortably above a range of surfaces.
