Rikulau Audax 325Ti Road Bike

Rikulau Audax 325Ti Road Bike

Audax series frames are designed for long distance road riding. Comfort, standard BSA BB shell and rack mount are all the considerations for the actual needs of a long distance rider.

Like all Rikulau products, stiffness and stability are the basic requirements. High quality tube processing and heat treatment are the must, but, no fancy CNC carving or hydroforming are applied to Audax Ti325 to make it a very practical and yet not costly choice.

The graphics design is named #18. It simply means a new attempt in 2018 to add a little bit of change to the normally applied low-key sand blasting process. The design is simple but with taste. Light brown matches the elegance of the metal.


  1. Tubing: 3Al-2.5V double butted; stress release by heat treatment after shaping
  2. 44 mm straight tube head tube: provides stiffness and cornering stability when used with 1 1/2”fork; with proper choice of headset, 1 1/4” fork can also be used.
  3. Standard BSA bottom bracket: easier to maintain in a long distance trip
  4. Rack mount: rack mount on seat stays and dropouts
