This authentic Interpro track frameset was handcrafted by JINCYCLE, one of South Korea's leading builders of professional Keirin racing bicycles.

The frame is constructed from genuine Columbus FOCO Keirin Thermacrom tubing, a premium Italian tubeset developed specifically for elite track racing. Renowned for its excellent balance of stiffness, responsiveness and low weight, FOCO was chosen by a number of high-end custom builders for professional competition.

The frame features beautifully crafted Nagasawa investment-cast lugs and a Nagasawa bottom bracket shell, reflecting the influence of Japanese craftsmanship on Korea's finest racing bicycles.

Official racing began in 1994, creating demand for high-quality domestically built racing bicycles. JINCYCLE became one of the country's best-known frame builders, producing Interpro frames for professional Korean Keirin
