  • 假若每次向下踩踏时,腰会上下动时,或者用脚尖才能踩踏,膝盖下方的肌肉容易疲倦时,以1mm单位向下移动鞍座观察情况。 调整鞍座的角度,使腰稳坐在鞍座上。鞍座的前后位置,若过于向前,腰比较容易累。相反过于向后的话,身体和握把之间距离变远,脖子和肩膀容易疲倦。

  • 车手的车把立的位置离身体远的话,上半身下沉,腹部受压迫,增加心肺机能的负担。有必要时换一个车把立调整把手。一般的车把立以5mm~10mm单位备有各种尺寸,。检查你的乘骑姿势后选择购买。 对初级车手来说,比较合适的姿势是上半身和手臂形成的角度为90°,这种姿势呼吸顺畅,把上半身的重量分散到腰、手腕、脚上。因此选择上半身和手臂能够形成90°角的车把立。 左相片的车把立的尺寸为100mm。右相片的车把立的尺寸为80mm,比左相片的短了20mm,使用较短的车把立时,手腕能够留有余地,肩膀不容易疲倦,踩踏时的腰的动作,自然造成有效率的踩踏。

  • 有经验的公路自行车车手,在平地上的速度一般为40km/时。单独或者几个人一起骑行,受到空气的阻力时,上半身要低,才能阻抗空气的阻力。左相片的姿势半身和手臂形成的角度为110°,握住手把膝盖弯曲至约90°时,上半身几乎和地面呈平行。 这种姿势腹部受压迫,呼吸变得困难,增加手腕及腰的负担,但是对有经验的公路自行车车手来说,速度应该摆在第一位。因为他们平时加强锻炼,身体能够适应这种状况。 有经验的公路自行车车手并不是始终保持这种姿势的,经常更换姿势,如改变握住把手的位置,起上半身,轻松一下等等。
  • 适合于初级车手的各种技巧                                                         ●(右)相片:握住把手上方的位置时,离身体近,呼吸顺畅。适合于上坡。 ●(左)握住该处,上坡、下坡、平地都能够采用的姿势。   把刹车杆向内扭一下就是一段,三联齿轮为2段,链条移向外侧的大齿盘,骑起来较重。 把内侧的小杆向内推时,变速为内侧1段,踩踏变得轻快。 禧玛诺的STI杆的变速操作 禧玛诺的STI杆ERGO杆,手不用离开把手就可以进行前后的变速操作。边骑行边操作,体会操作要领。
  • 为了防止产生大量的乳酸(它会妨碍肌肉收缩),曲柄的旋转速保持在50次/分,采用较轻的齿轮比
