Izumi

As a family‑run company, they pioneered innovations such as narrow bushless chains, breakaway connector pins, and high‑strength alloys, collaborating with Shimano since 1976. Izumi produces over 4.5 million chains annually—including the legendary Super Toughness and NJS-certified Izumi‑V series—manufactured entirely in Japan and known for exceptional durability, low friction, and precise shifting. We recommend Izumi for cyclists who demand top-tier drivetrain performance, whether racing, commuting, or upgrading fixed‑gear setups. Their lineup includes track‑specific and multi‑speed chains, differentiated by finishes and performance grades, all backed by rigorous quality control. Izumi continues to set the standard in chain manufacturing, making it the go-to choice for riders seeking reliability, riding efficiency, and time-tested Japanese craftsmanship.
