A track bike for Theo Bos
Koga wanted to develop the best track bike ever for Theo Bos and Dutch track cycling team, to be used at the Beijing Olympics of 2008. The aim was to develop a frameset with extremely high stiffness, low weight, and lowest air resistance. A project to make the fastest bike for the world's fastest rider.
Theo Bos' former sprint frame was thoroughly analysed on stiffness and aerodynamics, setting specific goals for the new design. By using digital simulation techniques, the frame was optimised before even being built. The result was an extremely stiff frame, with a decrease in wind resistance.
The Kimera as shown in the picture is one of the first models especially made for Theo Bos. Seat post and saddle are one with the frame to minimise drag and maximise stiffness even more. Eventually, Theo found out that he did prefer a traditional seatpost and saddle, and that's what he used during racing.
Although the Kimera has not lead Theo Bos to a gold medal in Beijing, he and the members of the Dutch Track cycling team have been very successful on the Kimera. Theo Bos became sprint world champion on the Kimera in 2007 and won silver on the Keirin in the same year. In 2008 he became European Champion. Marianne Vos won a gold medal at the Beijing Olympics. At the last track world championships, the Dutch team won 5 medals on Kimeras.
A proof of Theo Bos' amazing tactical skills is this film of one of the final sprints against Chris Hoy (later olympic champion) during the world championships of 2008.
