Introducing the Audax

Originally conceived as a more traditional road tourer the Audax has been transformed into a vision for modern endurance road riding. The starting point for the new direction was switching the wheel platform from 700c to the road-plus 650b. For long distance riding, steel is arguably the best material for the job. Its natural resonance dampens road buzz and produces a ride so compliant that it’s more akin to floating than rolling. The geometry has been revised for a less touring and more sportive riding position. Such geometry required shorter chainstays whilst retaining tire and chainring clearance the result of these factors led to the development of our custom yoke, a standout feature on this incredible frame.


Frame features new casted chainstay yoke as well as rack/fender mounts, x3 cage mounts and internal brake routing.

50 mm rake fork and 650B tires, offer more control over steering, especially in the smaller frame sizes

Mechanical and Di2 cable routing, plus internal brake routing

Straight blade extra wide full carbon fork with triple cage mounts and 12mm thru-axle.
