The original Audax heads upmarket for this year. Shimano's latest hydraulic 105 groupset takes care of both braking and shifting duties. This is boosted by an uprated Ultegra clutch derailleur which ensures chain retention on the roughest roads, while an FSA sub-compact crankset helps conquer the steepest hills. Hunt provides the wheels and Ritchey complete the picture with handlebars, stem, and seatpost. In common with many of our bikes, the Audax also changes to the durable T47 bottom bracket standard – suiting its punchy steel chassis perfectly.
