Trouble Shooting - DT SWISS Ratchet LN Technical Manual

3. TROUBLE SHOOTING

Issue
Freewheel is blocked
Freewheel does not engage
/ slips
Notches from the cassette
on the freewheel body.
Freewheel is too noisy / too
quiet.
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.
One or both springs were
forgotten during assembly.
The steel cassette works
itself into the alloy web of the
freewheel body.
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.
