輪組風阻的問題已經被討論到爛了.
想必大家也知道板高越高, 風阻越小這道理.
以市面上的板高,
由22,30,35,38,40,45,50,55,60,80 even 碟輪.
撇開低框的不講,
35~80的板高選擇要怎麼選擇呢!?
我的幾個思考模式給大家參考,
1. 速度越大, 風阻越大, 板高要更高
--> 以職業車手均速都4x以上, 高框是他們會選擇的.
但以我FTP才205W, 均速再快也35, 是不是不需要這麼高, 而可以選擇35就好?
2. 板高越高有無邊際效應?
--> 板高從22到40 會不會對風阻減低的提升是非常有幫助?
而40~50~乃至碟輪是不是幫助就會遞減?
3. 有無 速度/風阻下降/板高/順風逆風的 模型呢?
好想知道阿!!!!!
