如題~快拆鎖得太緊.會不會壓迫到滾珠或培林? 造成滾動較不順?
這不可能發生
滾珠軸承有調整預壓用的對鎖螺絲擋住，快拆無論鎖多緊都不可能突破這道屏障。就算考慮到滑牙問題，滾珠中軸的軸心比快拆軸心直徑大雙倍，不設暴力上限硬鎖先自爆的一定是快拆
培林軸心兩側支撐部位與培林則是沒任何瓜葛，就算你把快拆或車架都鎖爆了，跟培林都無關
Although small, axle compression on QR hubs is large enough to alter bearing clearance and should be considered when adjusting bearings. Bearings should be adjusted just loose enough so that closing the QR leaves the bearing with a slight preload. Excessive preload from QR closure is the cause of most wheel-bearing failures not caused by water intrusion. Clearance, in contrast, can be felt as disconcerting rattle when encountering road roughness."
