Audax AL XCD
"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."
Bombtrack Audax AL XCD
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.
