Here we go again, what I remember was; the Track handle bar was usually chromoly steel. So as stems. Can you imagine if a strong Keirin racer rode a bike with AVA death stem and bars???, he might never make 1000 meter goal ahead!
Some one please help me for a termnology, there was a type of racing (track) called "Oikosi", which Japanese term means "Passing". At least a team of two riders cruise around track and at certain spot, pass each other. It was FAST, speed over 100km/h (63mph+), at moment. I do not think they can use a road racer bike for this. It will break down in a few seconds!
KEN TODA, I was once impressed "human power" and speed with bike.
