This mountain bike frame produced by Kastan represents the expansion of BMX frame builders into the emerging mountain bike market during the late 1980s and early 1990s. As off-road cycling grew rapidly in popularity, several BMX innovators began applying their frame-building experience to mountain bike design. Bikes like this illustrate the transition of BMX craftsmanship and engineering into the broader world of off-road cycling.
After helping establish Redline Bicycles, frame builder Linn Kastan later launched Kastan BMX, introducing the KEX (Kastan Extra) frame series. Kastan later expanded into mountain bike design during the late 1980s and early 1990s, applying lessons learned from BMX frame construction to the rapidly growing mountain biking market.
