单位组织自行车环城赛和20米慢骑赛。这两项比赛,一项比快,一项比慢。我惊奇地发现:比快的时候,选手们都给轮胎打气,而比慢的时候,却都给轮胎放气。 赛后去问慢骑赛冠军,得到这样的答案:慢骑赛比的是骑完全程谁花的时间最长,放掉一部分车胎的气,使车轮与地面的接触面积增大,就会加大前进中的摩擦力,有利于减速;另一方面,略扁的车胎有利于选手发挥“定住”自行车的技巧,因为选手“定住”自行车技术的好坏,是能否取胜的关键。
Organizing the bike around the city race and 20 m slow riding race. One of these two competitions is faster than the other. I was surprised to find out that when they were faster, the players cheered on the tires and deflated the tires than they did when they were slow. After the race to ask the Jockey Club champion, get the answer: Jogger race is riding the whole journey who spent the longest time, let go part of the tire gas, the wheel and the ground contact area increases, it will increase On the other hand, slightly flat tires are good for the players to play the skills of “anchoring” bicycles because the player’s skills of “anchoring” bicycles are the key to success.
