The AUDAX 3Al-2.5V Ti uses tubing of the same quality as RIKULAU’s flagship MASTER series. Without the custom frame service and elaborate paint finishes, it offers outstanding practicality and value.

AUDAX takes its name from the Latin for “bold” and “resolute.”
True to its name, it is built for endurance events and ultra-distance riding, accompanying you over hundreds of kilometers with a consistently stable, smooth, and confident ride. Titanium’s distinctive resilience and toughness help absorb road vibrations, reduce fatigue on long rides, and improve pedaling efficiency, leaving you with more energy for every mile that matters.
For RIKULAU, AUDAX is more than a bicycle. It embodies the courage to keep moving into the unknown, because the true finish line often lies beyond the next bend.
