Only replace broken or worn key
parts with original replacement parts
from the manufacturer or parts ap-
proved by your manufacturer. This is man-
datory in the case of light systems, while the
manufacturer‘s warranty is usually nullied if
you install non-approved replacement parts.
If you install non-original or false re-
placement parts, this can lead to se-
vere 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 ap-
plies 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 abbrevi-
ation “UST” for instance.
Only use tubeless tyres in the pre-
scribed way, with the correct air pres-
sure and the recommended sealant
if required.
Tubeless tyres can only be mounted and re-
moved from the rims without tools, otherwise this
could lead to leaks. If the sealant is not sufcient
for preventing damage, a normal tube can be
used after removing the valve from the tubeless
system.
Tubular tyres
Some bicycles are also
tted with tubular tyres.
For more information on
these, please refer to
the enclosed instructions
from the manufacturer.
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 in the pre-
scribed way and with the correct air
pressure.
Only use tubular tyres on rims in-
tended for this purpose! These do not
have rim anges but smoothly curv-
ing surface, from the outside inwards. This is
where the tubular tyres are tted.
Attaching tubular tyres requires ex-
pert skills and lots of experience!
Always have your tubular tyres
changed by a specialist. Inform yourself about
how to handle and change this type of tyre!
