A modern audax bike. Our Audax AL uses its voluminous tyres and carbon fork to float over a range of surfaces. Able to accommodate both broad treads and mudguards, a huge range of fixings mean it’s happy carrying standard panniers or bikepacking bags. With a unique rapid geometry featuring short chainstays and an engaged front end, handling is kept lively. Balanced by the enhanced grip and comfort of its 650B tyres, the Audax AL nevertheless remains happy to be ridden day after day. Fitted with Microshift’s wide-ratio XLE 11-speed groupset, a clutch derailleur provides assured operation in rough conditions.
