Old racer's hold on, all my bikes were race bikes. Even if I don't race. But I can halfwheel a guy if I need to to the point where they look for an opportunity to turn off.
The killers are e-bikes. the 20 mph ones are no problem, the 24 mph are OK unless there is a headwind.
Its the bikes that can do 28+... disheartening. And the users get upset when you draft them.
