Recently I wanted to replace my bearings and spotted something strange.
My Over Locknut Dimension has reduced by 7mm.
You can spot the difference when you compare it to the new hub:
Can this happen if the bearings are set too tight?
Old cup is obviously damaged:
Also one very important fact, my quick release axle was broken :) :
So I wanted to know what is the main reason that caused the OLD reduction by 7mm? Did anyone else had similar experience?
Hub model: QUANDO KT-A12R / QR Type for Freewheel
Dimension that I'm referring to is the "M" according to this image
Inside distance(edit) of the hub is reduced by 7mm (non-drive side bearings - drive side bearings). Depth of the cup has increased by 7mm.
OLD with the original hub is 135mm.
If I use the same spacers O.L.D for the used hub is ~128mm.
BTW I am heavy guy - 105kg, 2m tall, that explains axle breakdown :)
