Rikulau 931 Road Bike
Reynolds 931 stainless steel is an alloy that has a balanced strength and ductility. Unlike its sibling 953 that has a very strong character, 931 is a very versatile multi-purpose material.
Rikulau 931 road frame makes the most of the material property to enhance the stiffness on the BB area and to provide enough comfort from the stays. Rikulau 931 will not be a racing expert, but, it is going to be a perfect fighter for endurance riding. In 2014, Rikulau 931 will face the Tibet challenge to break the current record of 8d11h58m .
Feature of Rikulau 931 road bike
1. Integrated head tube for enhanced stiffness and modern appearance
2. Flattened seat stay for more comfort
3. Larger down tube for increased stiffness

Simpliciy
Simplicity emphasizes the beauty of the frame material and the craftsmanship. Unlike other Rikulau graphics designs that are very cultural and artistic, “simplicity” is not fancy, not vivid, not rich, but yes, simply simple. It conveys a message of return to innocence.
Reynolds 931 Stainless Steel
931 has a tensile strength near 1300 MPa, and a very good corrosion resistance and ductility. Therefore, with manipulation on tube thickness and tube size, a 931 frame can be as stiff as a 953 frame, as comfortable as a titanium touring frame, or as much fun as a CrMo fixed gear frame. It is a very versatile multi-purpose material.
