Bombtrack Audax Al 650B Road Bicycle | Glossy Black/Warm Grey

By Bombtrack


Introducing the Audax AL: "With plentiful clearance, it can swallow up wide tyres, or be set-up with mudguards as needed."

A modern touring bike or an audacious audax machine. Our 650B Audax AL features a hydroformed aluminium frame that uses optimised butting profiles to reduce weight and increase compliance. With plentiful clearance, it can swallow up wide tyres, or be set-up with mudguards as needed. 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. Now fitted with Microshift’s wide-ratio XLE 11-speed groupset, this features a clutch derailleur for problem-free operation in rough conditions. With a full range of mounts and braze-ons across its fork and frame, it’s happy to accept either panniers or bikepacking bags.
