A slender steel frame, light carbon fork, all the mounts you could wish for, and a high-spec Shimano groupset. The perfect companion on any number of adventures, hydraulic disc brakes and a sub-compact crankset tailor the Audax to audacious long-distance riding. Mixing WTB Horizon and Byway tyres, it’s fast-rolling, yet proficient on broken surfaces. A timeless performer, subtle tweaks like the inclusion of an integrated rear light mount for 2021 help keep it bang up to date. Topped off with a Ritchey finishing kit, it’s happy going as fast or as far as you dare push it.
