Premium Frame and Fork Construction

High-Performance Components and Technology

Equipped with Shimano GRX ST-RX600 hydraulic STI shifters and brakes, the Audax delivers reliable and precise gear control along with powerful, modulation-rich braking in all weather conditions. The Shimano GRX 610-11 crankset with a 24 mm spindle and Shimano T47 sealed bottom bracket ensures smooth power transfer and durability.
