从技术角度分析,阿姆斯特朗的蹬车技术非常特别。环法自行车赛的传统是,在比较平坦的路段上把变速调到高档。这样,车手踏轮一圈需要使出很大力气且频率较慢,但这样会让车子比正常档的一圈多行进一些距离,速度也因此更快。在欣赏环法自行车赛时,我们总会看到车手们离座蹬车,看起来十分费力,但是车子的前进速度却是最快的,这也已成了环法车赛的标志。阿姆斯特朗则另辟蹊径,他在比较平坦的路段上使用的是中档,自行车链上的两个齿轮大小差不多,这样一来,蹬车会比较省力,而且容易加快踏轮的频率。理论上,这两种技术耗费的能量是一样的,但是在实际操作时,对阿姆斯特朗这种喜欢先节
From a technical point of view, Armstrong pedaling technology is very special. The tradition of the Tour de France is to shift gears to high gear on relatively flat sections. In this way, the driver needs to make a lot of effort and slow turn on the lap, but this will allow the car to go some distance more than a normal lap, resulting in faster speed. While enjoying the Tour de France, we always see the drivers taking off their seats and looking very laborious. However, the fastest speed of the cars is the sign of the Tour de France. Armstrong is another way, he is in the relatively flat sections of the mid-range, the size of the two gears on the bike chain is almost, so that the pedal will be more effort, and easy to accelerate the frequency of the wheel. In theory, the energy consumed by both technologies is the same, but in actual practice this is a favorite of Armstrong
