[討論] 關於剎車總泵規格選擇 19x20、19x18...等

想問一下一些進階總泵都有 活塞x距離 的規格可以選

例如19x18、19x20 前面活塞直徑相對直觀

但對於距離的部分沒答案，假設活塞規格固定下，

到底哪一種距離選擇會屬於"軟Q" 或是 "死硬"

自己畫了一張圖，還是沒有答案，不知道有沒有高手可以分享一下

最簡單就直接兩總都實際測試，不過沒這樣的資源

初步想法同樣按壓行程下

距離近:
活塞位移少 => 油量少、反應遲鈍
槓桿倍率大 => 力道強

距離遠
活塞位移大 => 油量多、反應敏感
槓桿倍率小 => 力道弱

網路上看到一些資料，但還是有點模糊

這是MOTO MADNESS 上面看到的解釋

What Do These Numbers Really Mean?
Cylinder diameter
1. As you increase your cylinder diameter you increase the volume of
fluid. By doing this, you are decreasing the pressure which results in less
braking power but better feel.
2. The trade-off is that since your increasing the sensitivity of the lever
your decreasing the braking power which we will now discuss in the 2nd
number

Pivot Point
1. As you increase the pivot point, the sensitivity is increasing but your
breaking power is now decreasing.
2. By increasing this number, the pivot point is larger and now you have
reduced your leverage

這是Youotube Moto7 看到的說法
