[Case Study] Development of a chain with minimized driving resistance for top-speed performance.
We would like to introduce a case where we received a request to develop a chain for track events with reduced drive resistance.
We would like to introduce a case study about the development of a chain that minimizes drive resistance, achieving a performance level among the fastest in the world. Our bicycle track racing chain, "IZUMI-V," has already received high praise from top athletes. However, in preparation for a world competition, we received a request for a chain with even lower drive resistance than the conventional model. To achieve this, it was necessary to apply a surface treatment to reduce the sliding resistance only on the inside of the bushing. If the entire bushing were surface-treated, we would not be able to maintain the necessary fitting force (interference fit) of the bushing. Since partial surface treatment was difficult, we applied a surface treatment to the entire bushing and then performed our proprietary treatment on the outside of the bushing. This unique process allowed us to successfully reduce sliding resistance by 20% while maintaining the required strength. The chain is available exclusively in gray. It is a product that thoroughly eliminates all non-essential decoration, focusing purely on functionality. 【Case Overview】 Request: A product that surpasses the conventional IZUMI-V. Challenge: It was necessary to reduce drive resistance while maintaining strength. Result: 20% reduction in sliding resistance. For more details, please download the PDF or feel free to contact us.
