IZUMI-V N 3/32" CHAIN

Forged in the rich heritage of professional Japanese Keirin racing, the Izumi-V N (Super Toughness) is globally revered by bike messengers, track racers, and fixed-gear enthusiasts as the toughest single-speed chain ever created. Manufactured 100% in Japan using high-carbon steel alloys subjected to a proprietary heat-treatment process, it delivers phenomenal tensile strength and absolute structural rigidity, completely eliminating power loss during explosive sprints. The 'N' edition features Izumi's most iconic visual signature: a high-contrast dual-tone design that combines jet-black outer plates with deep gold inner links and pins, adding an unmatched touch of mechanical sophistication to your build. Its official NJS stamp guarantees that it satisfies the most rigorous safety and manufacturing tolerance criteria in the entire cycling industry.
