Kalloy

 

According to CEN standards, stem and handlebar should be installed and tested together. In the original design, manufacturers tried to increase stem and handlebar strength in order to pass CEN standards. Raising the weight results from increasing stem and handlebar strength and safety; however, it added the weight to the stem and handlebar making it an uncomfortable ride on various road surfaces. Therefore, the original design cannot achieve components lightweight concept.
The Kalloy innovation team tries various ways to overcome the original design. For purposes of knowing the stems reaction in diverse situations while riding a bicycle on various road surfaces, the Kalloy innovation team uses accurate calculations and non‑stop testing by doing reasonable distributed stress.

 

After several adjustments, the Kalloy innovation team reaches the distributed stress point. First, Optimal Stiffness Construction technology can reduces a lots of products' weight; second, optimal stiffness construction design passes CEN-R (ASA-105) and CEN-M (ASA-105/AS-025/AS-027) tests; and third, Kalloy will use this technology in new stems and plan to spread it on to the middle and high class stems, from 2010.
