If you install non-original or false re-
placement parts, this can lead to
severe loss of function! Tyres with
poor grip or safety, brake pads with a low
friction coefcient and incorrectly installed or
poorly made lightweight components can all
lead to potentially serious accidents. The
same applies for improper assembly!
Tubeless tyres
If your bicycle is tted with tubeless tyres, please
read the instructions provided by your manufac-
turer covering the tyres and rims.
Only use tubeless tyres on rims in-
tended for this purpose! This will be
marked on the rims, with the abbre-
viation “UST” for instance.
Only use tubeless tyres in the pre-
scribed way, with the correct air
pressure and the recommended
sealant if required.
Tubeless tyres can only be mounted and re-
moved from the rims
without tools, other-
wise this could lead to
leaks. If the sealant is
not sufcient for pre-
venting damage, a nor-
mal tube can be used
after removing the
valve from the tubeless system.
Tubular tyres
Mountain bikes are also
tted with tubular tyres.
For more information
on these, please refer to
the enclosed instructions
from the manufacturer.
Only use tubular tyres on rims in-
tended for this purpose! These do
not have rim anges but smoothly
curving surface, from the outside inwards.
This is where the tubular tyres are tted.
Only use tubular tyres in the pre-
scribed way and with the correct air
pressure.
Attaching tubular tyres requires ex-
pert skills and lots of experience! Al-
ways have your tubular tyres
changed by a specialist. Inform yourself about
how to handle and change this type of tyre!
