IZUMI CHAIN IZUMI-KAI｜NJS-certified chain pursuing low drive resistance

A single-speed chain that offers light pedaling and smooth drive feel.

When you push off at a traffic light or accelerate, a smooth chain movement makes the whole bike feel lighter.

The IZUMI-KAI is a high-grade model developed to further reduce drive resistance, based on the IZUMI-V, which has been trusted for many years in Keirin and track racing.

Developed with the Tokyo 2020 Olympics in mind, it combines low-resistance movement with high durability through PTFE treatment. It's a chain to consider not only for track racing but also for fixed-gear bikes and single-speed bikes that demand a high-quality ride.
