Why do I feel that some cyclists' cushions are so narrow and small? How can they sit down while riding?

In fact, such a narrow cushion is not for athletes to sit on, because competitive athletes usually stand when exerting their strength, and their bodies are almost parallel to bicycles. The cushion designed in this way will not affect his strength. Our team bought Velo senso series cushions, which are narrow and small, so that we can concentrate on the competition when participating in the competition, and the stress will not be affected because of the cushion problem.
