Izumi V NJS Chain

The Izumi V NJS Chain is one of Izumi’s most iconic premium chains, chosen by riders who value strength, durability and efficient power transfer for track bike and single speed drivetrain setups.

For riders who train hard, ride frequently or put high load through the drivetrain, chain wear can directly affect drivetrain stability and pedaling feel. The Izumi V NJS balances durability, visual quality and power transfer, making it a strong upgrade choice for riders who want a more reliable chain.

This chain is made from Japanese steel and uses a special high-carbon alloy for the connecting pins. This type of material is commonly used in low-friction ball bearing applications, helping provide improved durability compared with standard chains. Izumi’s proprietary surface treatment also improves wear resistance while creating the classic contrast between gold outer plates and midnight blue inner plates.

The Izumi V is well known for its strength and efficient power transfer, and has earned a strong reputation among keirin racers. Whether used on a track bike, single speed bike or a refined drivetrain build, this chain delivers a solid, stable and iconic riding feel.

If you are looking for a chain with high strength, long-lasting durability, a classic appearance and Japanese-made quality, the Izumi V NJS Chain is an excellent drivetrain upgrade.

⚠️ Please note: this product includes one chain only. Crank, chainring, cog, chain tool and display props are not included.
⚠️ Please confirm your drivetrain uses a 1/2 x 1/8" chain standard before purchase.
⚠️ Chain length may need to be cut according to your frame, gear ratio and rear wheel position.
⚠️ Chains are drivetrain safety components. Professional installation, adjustment and inspection are recommended.
⚠️ Clean and lubricate the chain regularly to maintain smoothness and extend service life.
