長度越長,力矩越大,變形的量也越大。
所以不要忽略過長的前叉豎管,變形對操控的影響。
小折,和這位"隊長"組裝的公路車,都有過長的前叉豎管,
勢必在扣前煞車時,前輪會產生不安定的動態。
這個是基本的物理原則,不可能改變。
推文中有人提到荷蘭的狀況,但荷蘭是一個非常平的國家,沒什麼山。
上文有提到過長前叉豎管,在煞車時的影響。
尤其是在下坡的煞車,這樣過長的前叉豎管,風險非常的高。
荷蘭這麼平,高龍頭,高把手,常前叉豎管.....不太會遇到這種嚴格的考驗。
而事實上,我們常使用淑女車,把手龍頭都高,前叉豎管也長。
同樣也面臨下坡扣前煞車,前輪的動態不佳。
但,大家不太有機會用這種車,去挑戰高山後下山。
用下坡,來考驗這種不利的零件配置。
今天騎騎河濱公園,前叉豎管多長,我真的不會太在意。
但,這票人都有帶活動,帶人爬山下坡。
這樣零件配置帶來的風險,卻絕口不提,非常的不負責任。
一般前叉豎管,都不建議留這麼長。
就算放寬一點,10cm也很多了。
今天是25cm!!!
這是什麼神扯高度,真的太離譜。
再加上對於碟煞錯誤的認識,只能說專業知識非常的不足。
大蘋果車隊,隊長從十多年前,單車熱開始。
在很快的時間內,此車隊變成全台最大車隊,最大的論壇。
因為隊長一人的爭議,整個隊分崩離析,隊長本人搞到名聲臭掉。
大蘋果車隊和論壇,漸漸地不具影響力。
大蘋果隊長,仍用這曾經有過的全台最大車隊之名,
去唬一些不清楚自行車生態的朋友。
再看到隊長對車子"獨到"的見解,只能說.....隊長經營車隊,真的是非常"有成"。
