Description

The Audax

Using components selected for performance but with the solid reliability required for endurance riding.

"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."

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.
