About the Duetti frameset.
The frame is crafted in 6069, an exotic super-alloy of aluminum. This alloy, along with specific heat treatments and carefully controlled shot peening*, enables us to produce tubes that when formed into our latest proprietary “Colorado Concept” design, are astoundingly light, responsive, forgiving, and durable.
The 6069 super alloy is not produced in North America and the only frame shops familiar with the material and process are in Taiwan… which is why these Serottas are proudly produced in an immaculate facility in Taiwan.
*This type of shot peening was first developed in the defense industry to increase fatigue life in propellers and related hardware that is challenged by constant vibration combined with cyclical loading-a direct correlation to a bicycle. Controlled peening can increase product life expectancy by more than 300%.
