TUBELESS/UST TYRES
Tyre Removal
Let the air out completely from the tubeless/UST tyre
(a)
. Now press
one of the tyre sides around to the middle of the rim until the tyre bead
sits loosely in the rim well. Now lift this tyre side completely over the
edge of the rim, starting with the side opposite to the valve. Do not use
a tyre lever, to avoid damaging the delicate sealing lip at the tyre bead!
Only once the entire tyre side has been pulled over the edge of the rim
should you press the other tyre side into the rim well as required and
then pull this from the rim as well.
Repair
In the event of a puncture you can also use tubeless tyres with a tube
(b)
. To do this, first remove from the tyre the object that had penetrated
it and then take the valve out of the rim. Slightly pump up the new tube
and lay it in the tyre. Mounting is done as described below.
There are special repair patches for tubeless tyres that are applied to
the inner side. In an emergency it is also possible to use standard re-
pair patches. In all case follow precisely the instructions for use of the
repair set.
A
Incorrect mounting of the tyre can lead to functional prob-
lems or damage to the tyre. For that reason follow precisely
the instructions of the manufacturer in the attached in-
structions
(c)
.
Tyre Mounting
The tyre must be free of lubricant and dirt both inside and in the area of
the tyre bead. Do not use tyre levers! In order to prevent any damage,
wet the tyre bead all the way round with soapy water or tyre mounting
paste – or with water at least – and press the tyre into the rim
(d)
with
your hands, as described with clincher and folding tyres.
First lift one tyre bead completely over the edge of a rim, and then the
other. Press both tyre beads all the way around into the well of the rim
and ensure that the special valve is centred between the tyre beads.
Press onto the tyre from above over the entire circumference of the
tyre. Pump up the tyre with a compressor or a CO

cartridge
(e)
up to
its maximum air pressure so that it can seat properly on the rim. The
permissible pressure is normally shown on the side wall of the tyre.
Loud plopping noises can be heard during the seating process. Do not
be worried!
Check whether the tyre is properly seated by inspecting the fine wit-
ness line on the tyre just above the rim edge. This line should be even
to the rim all around the tyre. Starting from the maximum tyre pressure
you can now reduce the pressure through the valve to suit your needs.
Please observe the recommended tyre pressure range

Tubeless tyres may only be mounted on a UST rim or wheel
(Mavic and other makers).
TUBULAR TYRES
Tyre Removal
Let the air out completely from the tyres To remove the tyre, press the
tyre to the side at a place on the opposite side to the valve until a gap
forms and the tyre releases. If the tyre is stubborn, push a tyre lever into
the gap so that you can lever the tyre out.
It is not possible to replace a single tube, instead you must mount a
complete tubular tyre
(g+h)
onto the rim. The tyre cannot be glued
while you are travelling and therefore it also does not seat properly on
the rim after being pumped up.
For that reason only ride home slowly and cautiously, taking the short-
est possible route. Once you have got back home you must completely
reglue the tubular tyre as described below.
Tyre Mounting
Careful mounting that will ensure that the tubular tyre holds perma-
nently must be done in steps and can take a long time. Some practice
and experience with the tyre adhesive used and the relevant model of
tubular tyre can speed up the work.
