Reason
Spacer was forgotten during
assembly.
Spacer was compressed by
overtightening the thru axle.
One or both ratchets are mounted
upside down.
Too much or wrong grease on the
ratchets.
Ratchets are worn.
One or both springs were
forgotten during assembly.
Ball bearings were not mounted
correctly.
Ball bearings are worn out.
Ball bearings are worn out.
Ball bearing non-drive side driven
in too tight.
Mounting sequence of the ball
bearings not observed.
Ball bearings are worn out.
The steel cassette works itself
into the alloy web of the freewheel
body.
Ball bearings in the freewheel
body are worn out.
The perception of the freewheel sound is very subjective. While some
riders prefer a loud freewheel sound, other riders want a quiet freewheel.
In principle, the freewheeling sound can be influenced by the amount of
grease between the ratchets. Less grease increases the freewheeling
sound, but at the same time leads to higher wear.
