Track racing chain "IZUMI-V/-KAI"

Track racing chain "IZUMI-V/-KAI"

Driven resistance is reduced to the limit with unique technology! This is a product that emphasizes functionality.

Introducing the track racing chain developed for top athletes in cycling, the 'IZUMI-V/-KAI'. The conventional bicycle track racing chain 'IZUMI-V' has received high praise from top athletes around the world for many years. The 'IZUMI-KAI' is an improved version based on the 'IZUMI-V', designed to have even less drive resistance. Both chains feature a unique technology that minimizes drive resistance. The power from pedaling is transmitted efficiently, resulting in effective pedaling force. 'IZUMI-V' - Experience a direct feel of the power transmitted from the pedals. - Decorated with a beautiful gold/black design. 'IZUMI-KAI' - Enjoy a smooth and light feel. - Decoration is eliminated, focusing solely on functionality. Both chains are developed for competitive use. Please select the chain that suits your style. *For more details, please download the PDF or feel free to contact us.

[Case Study] Development of a chain with minimized driving resistance for top-speed performance.

[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.
