Bombtrack Audax - 2024

This is our premium Audax machine built with Columbus’s Cromor double butted tubing. The svelte diameter tubing offers up images of the steel Audax bikes of old, but this is no retro machine. It's bang up to date with a tapered head tube, T47 BB, 12 mm through axles, a rear light mount, and even more cargo-carrying options with rack mounts on the frame if you prefer to use panniers. Shimano’s GRX 600 2x groupset provides the shifting and stopping duties with GRX 810 front and rear mechs shifting via sub-compact 2x crankset to keep your cadence silky smooth whatever the route you choose. Luxurious 650 x 47 mm Byway TCS tyres and Ritchey Comp finishing kit provide all-day riding comfort for those long adventures in the saddle.
