Bombtrack Audax (Sage Green)
Availability: | In stock (1) |

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 kilometres roll by, hydraulic disc brakes provide reliable stopping power while a sub-compact chainset handles propulsion. A combination of WTB Horizon and Byway tyres 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 tyres contain enough air to carry you and your kit comfortably above a range of surfaces.
