Dry the frame.
Spray with care oil.
Clean off the care oil again after a short time.
7.3.2 Servicing the stem
Apply silicone or Teflon oil to the stem shaft
tube and the quick release lever pivot point.
If you have speedlifter Twist, also apply oil to
the unlocking bolt using the groove in the
speedlifter body.

between the stem quick release lever and the
sliding piece to reduce the quick release lever
operating force.

3Check the rims for wear.
The rims of a rim brake with invisible wear
indicator are worn as soon as the wear
indicator becomes visible in the area of the rim
joint.
The rims with visible wear indicator are worn as
soon as the black, all-round groove on the pad
friction surface is no longer visible. We
recommend that you also replace the rims with
every second brake lining replacement.
4Check the tension of the spokes.

Check the tyre wear. The tyre is worn if the
anti-puncture protection or the carcass cords
are visible.
A specialist dealer will need to change the tyre
if it is worn.

Check the rims for wear. The rims are worn as
soon as the black, all-round groove on the pad
friction surface becomes invisible.
Contact your specialist dealer to have the rims
replaced. We recommend that you also replace
the rims at the same time as every second
brake lining replacement.
