Bombtrack Bicycle Company Audax
Details
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 kilometers roll by, hydraulic disc brakes provide reliable stopping power while a sub-compact chainset handles propulsion. A combination of WTB Horizon and Byway tires are fast-rolling over gravel, mud, or dirt. The integrated rear light mount brings discipline into the modern age. Topped off with Ritchey finishing kit, you’ll reach the coast before this bike gives up.
Fast on tarmac, and smooth over broken ground, its broad tires contain enough air to carry you and your kit comfortably above a range of surfaces.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore BOMBTRACK cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local BOMBTRACK dealer or a professional bike fitter and have them determine the needed size.
