Optimal Stiffness Construction
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'
