76 WHEELS PUNCTURE
You will find it easier to remove the rear wheel, if
you pull the rear derailleur rearwards a little.
Lift your Canyon a little off the ground and give the
wheel a light blow with your hand so that it drops
out.
REMOVING CLINCHER AND FOLDING TYRES
Screw the valve cap and the fastening nut off the
valve and deflate the tyre completely.
Press the tyre from the rim side towards the centre
of the rim. You will find it easier to remove the tyre,
if you do this around its entire circumference.
Apply the plastic tyre lever to one bead of the tyre
about 5 cm left or right from the valve and lever the
tyre out of the rim. Hold the tyre lever tight in its
position.
Slip the second tyre lever between rim and tyre at
a point about ten centimeters beyond the first one
and lever the next portion of the bead over the edge
of the rim.
After levering a part of the tyre bead over the edge
of the rim you should normally be able to slip off
the whole tyre on one side by moving the tyre lever
around the whole circumference.
Now you can pull out the inner tube. Take care the
valve does not get caught, as this can damage the
inner tube.
Pull the rear derailleur slightly to the rear to remove the rear wheel
Press the tyre towards the centre of the rim
Apply the tyre levers and lift the tyre bead over the rim edge
Remove the inner tube from the tyre
Repair the puncture according to the operating in-
structions of the repair kit manufacturer.
After having removed the tyre, you should check
the rim tape. The tape should lie squarely in the
base of the rim covering all spoke ends and should
neither be torn nor brittle. In the case of rims with
double base – known as double chamber rims – the
tape must cover the entire rim base. For this type
of rim only use rim tapes made of fabric or dura-
ble plastic. In case you are not sure with regard to
your rim tape, please contact our service hotline at
+44 (0) 20 8501 2582.
If necessary, you can remove the whole tyre by pull-
ing the other tyre bead off the rim.
MOUNTING CLINCHER AND FOLDING TYRES
When mounting a tyre make sure no foreign matter
such as dirt or sand gets inside the tyre and you do
not damage the inner tube.
Slip one bead of the tyre onto the rim. Using your
thumbs, press the bead over the edge of the rim
over the entire circumference. You should be able
to do this without any tools, regardless of the type
of tyre. Stick the valve of the tube through the hole
in the rim.
Inflate the inner tube slightly so that it becomes
round and push it into the tyre all the way round.
Make sure not to leave any folds in the tube.
To finish mounting the tyre start at the point oppo-
site the valve. Using your thumbs, press the second
bead of the tyre over the edge of the rim as far as
you can.
Make sure the inner tube does not get pinched and
squashed between tyre and rim. This is prevented
by pushing the inner tube into the tyre hollow with a
finger as you work along.
