SAFETY INSTRUCTIONS
It is not only possible to ride with UST/tubeless tyres, but also with typical
folding tyres without inner tube and filled with latex milk, if necessary. Read
and observe the instructions of the supplier.
Useful Information about Tubeless Tyres
CAUTION
The valve nut of tubeless tyres must be checked regularly for a tight seat (d).
With a loose valve air will quickly escape from the tyre.
When mounting tubeless tyres the tyre bead and the rim edges must be
moistened with a special solution on both sides (e). Normally you can also
use detergent diluted with water. This is the only way to make the tyre slip
into its bed and become air tight.
N OTICE
You can also inflate the tyre with the repair spray actually designed for a
repair during the ride. The spray provides an integrated puncture protection.
To do so slide the spray head on the valve. Align the bottle in a way that the
opening of the head is flush with the valve. Keep the top of the head tight
with one finger and press the bottle for about two minutes against the head.
Pull the bottle from the valve with a jerk. Then set off on your bike for a few
miles to make the latex milk spread inside the tyre.
In case of a puncture in your tubeless tyre you can repair the tyre inside as
you would usually repair an inner tube. If you have filled latex milk inside be-
forehand the milk must be removed thoroughly in the area of the puncture,
otherwise the patch will not stick. Inflate the tyre with the spray subsequent-
ly (f). Minor damage can also be repaired by only using the spray.
SAFETY INSTRUCTIONS
Inflating with a cycle or track pump is difficult. The sudden pressure increase
which is necessary to make the tyre slip neatly and tightly into the rim seat
can typically only be achieved with an electric compressor. The tight seat is
indicated by one clearly audible pop per tyre side.
