The Audax is built for long days on mixed roads, pairing a Columbus Cromor steel frame with a full-carbon fork and generous 650B × 47 mm tyres. Rack and mudguard mounts add touring versatility, while the tapered head tube, through-axles and T47 bottom bracket bring modern standards to its slender steel silhouette.
Shimano GRX 2 × 11 shifting combines with 48/32T chainrings and an 11–34T cassette. Hydraulic disc brakes and Ritchey finishing components support comfortable distance riding. The listed build uses a WTB Byway front tyre and WTB Horizon rear tyre.
