最近開始接觸單車與想騎車
有些問題想請教版上的大大
1.RC
常聽見一些人提到"RC"
就我所知似乎是BB中心點到後下叉的長度?(不過不是很確定)
請問是這樣嗎?
此外RC的長度除了外觀外對於車子還有啥麼影響?
RC越長(or越短)對騎乘者來說又有什麼影響呢?
一般提到車架幾乎只會談到騎乘者身高對應到適用的車架尺寸
RC好像沒怎麼聽到...
2.飛輪的齒數
我注意到飛輪的齒數有時候是連號有時候卻是跳號
不知道這樣形容對不對..
意思就是有的飛輪齒數從第一片13T/第二片14T/第三片就跳過15T直接到16或17T
請問這是有特別定義或含義的嗎?
為何不要用等差級數往上增加就好?(ex:13/15/17...or 14/15/16...)
以上2個問題請版上的大大幫小的解惑
感激不盡~~
p.s其實腦袋還有一堆問題,等我消化完精華區後再慢慢問XD
