由解剖圖來看
前花鼓耳若說是為了閃過培林的位置 而往內縮
這論點是可以成立.....
但後花鼓 非傳動側的花鼓耳 往內縮
一時間 我還看不出個所以然來.....
但 它的超大花鼓耳 倒是很罕見.....
這樣可以讓所需的鋼絲更短 傳動時的鋼絲形變量會更少......
力量的回饋與反應速度.....真是令人期待阿~~~~
Cobblestones bike racings are popular bicycle tours in Europe. When racing on such a rough street, a hub must bear a deadly impact (approx. 600kg weight) in every moment. With a standard hub structure, a shaft easily gets deformed and axle becomes deflected causing bearings to twist.This creates a constant"put on brake"condition on the bearing, caused by abraded steel bearing balls . As a result, more pedaling force is required. GOKISO Hub adopts a spring-structured and elastic body suspension around the bearings with a 0.5mm play to absorb the shock. This system minimizes the shock without sacrificing its rotation performance.

這段內文頗有意思
培林裝設在花鼓內部的套筒上
跟花鼓本體是有間隙的
這樣能有吸收一些路面衝擊的能力
達到更穩定與更省力的效果(因路面震動越大越頻繁 會影響到速度)
