No one knows bicycle chains like Izumi. We started in 1916 as a maker exclusively of high-quality bicycle chains. In the century since, bicycles have changed dramatically: from one gear to 12, with increasingly sophisticated drivetrains that require light, durable, efficient chains for peak performance. At every step, Izumi continues to drive innovation in bicycle chains with advances in materials, surface treatments, and design. Today, Izumi remains family owned and operated, and manufactures more than 4.5 million bicycle chains a year, including the legendary Super Toughness, and chains for Shimano’s high-end road, mountain and e-bike groups, all made entirely in Japan.
