推 campy:誰知道他站起來踩的齒比約為多少?? 中間那一段 05/13 15:23
阿姆斯壯採用的齒比是正常人會用 39x23T,版上某位神人昨天甚至用同樣的
齒比去比東北角的比賽,終點前的那個變態陡坡比 Alpe d'Huez 還陡許多。
正常人辦不到的是,在超過 8% 的坡度上阿姆斯壯還可以用 100-110rpm 的
迴轉速來騎。Ullrich 用的齒比比較重,大概是 39x19,但迴轉速只有 70-
80rpm 而已。一個是拼心肺,一個是拼肌力,兩種騎法不太一樣。
另外可以注意一下阿姆斯壯站起來騎車時的姿勢,身體幾乎沒有垂直上下的
動作,只有左右擺動。如果身體重心有垂直上下的位移的話,長時間下來會
消耗掉非常多的能量。在練抽車的時候不妨留意一下這個重點,這樣就可以
抽得比較具經濟性,撐得比較久一點。
