Tubeless Tyres (UST tyres)
Tubeless tyres are also referred to as “tubeless ready”. The rims are provided
with specific valves, have an entirely enclosed rim base and partly also a specific
rim shape. There is no inner tube.
Tyre Removal
Deflate the tubeless/UST tyre completely. Press the tyre from one side towards
the centre of the rim, until the tyre bead is loose in the rim base.
Start removing the tyre close to the valve and lift one tyre side over the edge
of the rim with your fingers.
After you have pulled the entire tyre side over the rim edge press, if necessary,
the other tyre side into the rim base and remove this side also from the rim.
Puncture Assistance – Repair
In case of a puncture, tubeless tyres can also be used with inner tubes.
Remove any available perforating object from the tyre first and remove the valve
from the rim. Slightly inflate the new inner tube and place it in the tyre. Mount it
as described in the chapter
“Removing Clincher and Folding Tyres”
. You may
need tyre levers for this purpose.
Note:
Do not use tyre levers in
order to avoid damage
to the sensitive sealing
lip on the tyre bead!
Note:
It is recommended that
you use the tools of the
respective tyre manu-
facturer for removal as
they are designed to be
used together.
Note:
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. Remove the bottle quickly from the valve. Then set off on
your bike for a few miles to make the latex milk spread inside the tyre.
Note:
For tubeless tyres there are specific patches that are mounted on the
inside. If need be, you can also use a conventional repair patch. Always
observe the operating instructions of the repair kit manufacturer.
Mounting Wheels
Mounting the wheel is done in the reverse order of removal. Make sure that the
wheel is correctly seated in the drop-outs and accurately centred between the fork
legs or the seat and chainstays.
Check the proper seat of the quick-release and the drop-out catches and hook
in the brake cable immediately or close the release lever or the pin. For more
information see the chapter
“How to Use Quick-Releases and Thru Axles”
.
If you have disc brakes, check before mounting the wheel whether the brake
pads rest snugly in their seats in the brake calliper body. The gaps between the
brake pads and the wheel should be parallel and the wear indicators in their cor-
rect position. Make sure that you slide the rotor carefully between the brake pads.
After mounting the wheel and tightening the axle nut or the quick-release and
a thru axle, if available, pull the brake lever (several times, if you have disc brakes).
To do so lift the bicycle off the ground and spin the wheel with your hand. With the
wheel spinning the rotor should not drag along the brake calliper or the brake pads
and the rim should keep off the (rim) brake pads.
Danger:
Improper mounting can lead to malfunctioning, tyre damage or even
brake failure. Therefore, strictly observe the instructions of the component
manufacturer.
Danger:
Before you set off again connect the brake cable and check whether the
brake pads hit the braking surfaces. Make sure that the wheel is properly
seated and firmly fixed in the drop-outs. After mounting the wheel Make
sure that the brake pads or the rim are free of grease or other lubricants.
Be sure to do a brake test! In the case of disc brakes, Make sure that the
rotor does not drag on the brake calliper or the brake pads! Inappropriate
wheel mounting can make you loose control of your bicycle and result in an
accident!
Danger:
Never ride a STEVENS
bicycle without having
checked first whether
the wheels are securely
fastened! A wheel that
comes loose during the
ride will throw you off
your bicycle!
Danger:
With a tyre changed en
route be sure to ride
back carefully.
Note:
If you have any
questions, contact your
STEVENS dealer.
