About

Our Story

306 Cycles started in 2026 in New York City, born from riding fixed gear on city streets and hunting for the parts that Japanese keirin racers trust with their lives.

Today we operate from Tokyo, Japan — right at the source. Keirin, Japan's professional track racing sport, requires every frame and component used in competition to pass NJS certification. This ecosystem has produced some of the finest track parts ever made: Nitto stems and bars, MKS pedals, Sugino cranks, Kashimax saddles, Dura-Ace Track hubs. Many of these parts circulate in Japan's second-hand market and rarely leave the country.

That's where we come in. We monitor the Japanese market daily, hand-pick clean and honest parts, inspect every item in Tokyo, and ship them directly to riders worldwide. Our catalog centers on NJS-certified parts, alongside the broader world of Japanese track and fixed gear components.

Why buy from us

• Genuine, from the source. Every part is sourced in Japan. No replicas, no gray-market detours.
• Inspected in Tokyo. We photograph and describe every item as it is — including its flaws. What you see is what arrives.
• Rider-run. This is a one-person operation run by a rider, not a warehouse. Questions about compatibility or condition? Ask — you'll get a straight answer.
