Bombtrack Bicycle Company Audax AL
Details
A modern twist on an age-old discipline, the Audax AL is an accomplished bicycle. Wide, generous tires confidently roll over any surface, guided by a carbon fork to reduce weight with plenty of clearance to accommodate wider treads plus mudguards. Take your pick on how to distribute your cargo with multiple mounting fixings across the frame and fork, as well as options for panniers and bike packing bags. Short chainstays and an engaged front end make for a responsive bike geometry, which feels alert and responsive even when fully loaded. To complete the bike, 650B wheels, a Microshift XLE 11-speed groupset, and a clutch derailleur ensure comfort and reliability wherever you point your nose.
Employing short chainstays, it's a bike that's happy to change lanes quickly, but yet remains solidly planted thanks to a larger-than-average contact patch.

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.
