With the ability to be cold-worked, butted, and formed into complex shapes, aluminium alloys have proven themselves, time and time again, to possess excellent characteristics for lightweight bicycle frame construction.

Simply looking at the properties of a single material is no way to judge a frame’s quality. The carbon weave, or outer appearance, which most people recognize is typically used only for the final outermost layer, which is visible through the clear coat. Although this lends some structural integrity to the frame, it is primarily cosmetic. So a UD, 1K, 3K, or 12K weave designation does not necessarily determine a frame’s quality.

At Avanti, we use the most advanced types of forming technologies, including state-of-the-art Hydroforming and Super Plastic Forming (SPF, gas forming). Using high pressure to form the tubing from the inside out, allows for unusual and complex external shapes while being able to utilizing premium double-butted tubing internally. This results in lightweight yet remarkably strong tubing, without requiring gusseting or reinforcement. Additionally

we can directionally-tune the tubing to offer a set of desired ride characteristics. Whether using this latest technology or traditional methods, at Avanti every tube’s diameter, wall thickness, butting and shape is fine-tuned to bring together a balance of high performance, light weight and comfort

FEA is a method that realistically models mechanical behaviours using a computer. This allows us to determine the strength, stiffness, deflection and natural frequency of certain designs before they are manufactured.
