Why do Kierin riders race with such old-skool bikes? Steel and not carbon/alu frames, non-aero wheels ... it is because of simplicity and NJS standards?

thanks for the spoke card tomity!

Japanese Keirin race is gambling sports.
Therefore, the race should be perfect all.

Huge bet money is paid to Keirin race.
NJS parts has durability in the high quality.

The reason for NJS frame(steel only) is that the repair is easy when crash is done.
The repair of carbon and aluminum frame is difficult.

The Keirin society is always requesting fair safety of Keirin race.
Fair safety is essence of Japanese gambling Keirin race.

This is a difference of the amateur race and the gambling race.
