AUDAX AL
Audax AL is our lightweight aluminium Audax bike featuring a hydroformed double butted frame and full carbon fork. We’ve optimized the butting profiles to reduce weight and at the same time, ovalized the top tube and dropped the seat stays for added compliance – the Audax lives up to its name, allowing you to ride for longer. The frame and fork have fender mounts and a pleather of mounting points for traveling fast and light. Microshift’s 11 speed drivetrain with a 40T chainring, 11 – 46T cassette and XLE clutch rear mech will make light work of the hills and won’t rattle on the cobbles whilst WTB Horizon 650B x 47 mm tyres make short work of uneven surfaces.

"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.
