Removing Tubular Tyres
Deflate the tyre completely. To dismount the tyre, start opposite the valve by
pushing the tyre to the side until a gap appears and the tyre starts to come off. If
the tyre remains tight, stick a tyre lever into the gap and lift the tyre off the rim.
Replacing an individual tube is impossible. Instead you have to mount a com-
plete tubular tyre. En route the tyre cannot be glued and is consequently not tight
on the rim even when inflated.
Therefore, be sure to ride back very slowly and carefully by taking the shortest
way possible. Back home, you have to glue the tubular tyre, as described in the
following.
Note:
If your bike has carbon rims, you have to use special tubular tyre glue (e.g.
from Continental). Be sure to read the operating instructions before using it
or ask your STEVENS dealer.
Note:
Read the instructions
of the wheel, tyre and
inner tube manufacturer.
Mounting Tubular Tyres
To ensure a durable fit, a tubular tyre needs to be mounted carefully. The
mounting needs to be carried out in several steps and may require a little time.
A little practice and experience with the glue you are using and the respective
tubular model can speed up the job.
You can glue a tubular tyre to the rim with adhesive tape or with liquid tyre
glue. Using adhesive tape will speed up the mounting, the tyre, however, will not fit
as reliable as with liquid glue. In the event of a puncture the tape remains often on
the dismounted tyre and your spare tyre may not stick to the rim sufficiently well.
A better alternative is to apply several layers of liquid tyre glue. The layer of
glue will remain on the rim even after tyre removal and fix the spare tyre still
sufficiently for your ride home.
Afterwards, however, the spare tyre has to be removed and fixed with a new
layer of tyre glue. Tyre glue also sticks to fingers and clothing. Put on old working
clothes when mounting tyres.
Remove the protective valve cap and screw a valve extension, if necessary, to
the valve head unscrewed before, if you intend to mount the tyre on a deep rim.
Inflate the tyre to a point where it starts to become round and then stick the
valve through the hole in the rim.
Starting from the valve and working in both directions, press the tyre into the
tyre bed all the way round, as described further below.
If you are unable to mount the tyre completely on the rim or only with excessive
forces, you may not be able to mount it properly. Do not stretch the tyre by putting
your foot in the tyre and pulling it forcefully upwards with both hands. Ask instead
some one to help you.
Keep in mind that you must be careful when riding with a tyre that is not glued.
Danger:
A poorly glued tyre can
come off the rim. Risk of
accident.
Caution:
For your own safety,
have a tubular tyre
mounted by a STEVENS
dealer.
