2. Removing the wheel
• If your bicycle has quick-release levers or ax-
les, open them (see page 10 and 11).
• If your bicycle has hex nuts, loosen these with
a suitable spanner anti-clockwise.
You can then remove the front wheel according
to the steps listed above.
The following applies for rear wheels:
• If your bicycle uses a derailleur gear system,
change gear to the smallest sprocket. In this
position, the rear derailleur poses the least
hindrance in removing the wheel.
• If your bicycle has quick-release levers or ax-
les, open them (see page 10 and 11).
• If your bicycle has hex nuts, loosen these with
a suitable spanner anti-clockwise.
• Pull the rear derailleur backwards somewhat.
• Lift the bicycle slightly.
• Lightly strike the wheel from above with the
palm of the hand.
• Take the wheel out of the frame.
If your bicycle has a gear hub, please consult the
instructions supplied by your manufacturer for re-
moving the wheel.
Types of valve on bicycle tubes
Dunlop (Woods) valve
Schrader valve
Presta valve
3. Removing the tyre and inner tube
• Unscrew the valve cap, the fastening nut and
possibly the cap nut from the valve. In the case
of Dunlop or Woods valves, remove the valve
stem.
• Release all of the remaining air from the inner
tube.
• Insert the tyre lever opposite the valve on the
inside of the tyre.
• Insert the second tyre lever approx. 10 cm
from the rst, between the rim and tyre.
• Lift the tyre wall over the edge of the rim.
• Repeat this lifting action around the wheel until
the entire tyre is free.
• Remove the inner tube from the tyre.
For tubular tyres, see page 24
4. Change the inner tube
Switch the inner tube for an intact one.
For the change of tubular tyres and
tubeless tyres follow the instructions
of the rim or tyre manufacturer.
5. Reassembling the tyre and inner tube
Please avoid allowing foreign bodies
inside the tyre. Ensure that the inner
tube does not have any folds and is
not squashed.
Ensure that the rim tape covers all spoke
nipples and does not have any damage.
• Place one edge of the rim into the tyre.
• Push one side of the tyre completely into the
rim.
• Insert the valve through the valve hole in the
rim and put the inner tube into the tyre.
• Pull the second side of the tyre into the rim
with the balls of your hands.
• Ensure that the inner tube is correctly posi-
tioned.
• In the case of Dunlop or Woods valves: Push
the valve stem into the right position and tight-
en the cap nut.
