Description
Description
Developed from the legendary Izumi-V design, the Super Toughness Kai is built to reduce driving resistance while maintaining extreme durability. Designed for track racers and keirin professionals, it ensures smooth, efficient power transfer with minimal friction.
NJS-Certified for Elite Performance: One of the few chains to meet the strict Japanese Keirin Association (NJS) standards, this chain is trusted by professional racers for its superior strength and reliability. Its seamless design minimizes energy loss, making it a top choice for high-speed track racing.
Unmatched Durability with High-Carbon Alloy Pins: Featuring special high-carbon alloy connecting pins—often used in low-friction ball bearings—this chain offers a 300% increase in durability compared to standard models. The enhanced wear resistance ensures long-lasting performance, even under extreme torque.
Advanced Surface Treatment for Longevity: The proprietary PTFE treatment reduces friction and enhances abrasion resistance, keeping the chain running smoothly while extending its lifespan. High-rigidity, wear-resistant pins and seamless bushings further improve strength and durability.
With its low drive resistance and ultra-tough build, the Izumi Super Toughness Kai chain is the ultimate choice for racers who demand speed, efficiency and long-term performance on the track.
