While the Kestrel 4000 was the road bike star of 1987, revolutionizing bicycle design through the use of carbon fiber, in 1992 the 500SCi took it a step further by eliminating the traditional seat tube. This bicycle was the first modern seat-tube-less design which demonstrates the structural flexibility offered by composite construction. Unfortunately, due to the lack of a seat tube and the smaller 650 size wheels, it developed a reputation for being unstable at high speeds and was therefore outlawed by the UCI.
