Groove as a wear
indicator
Rims are subject to a great deal of
strain and are vital to your safety on
the bike. Riding wears rims down
over time, particularly on bicycles with rim
brakes. If you notice any damage or the
wear indicators show dangerous levels of
wear, you should no longer ride with these
rims. Have them checked by a specialist re-
tailer and replaced if required.
Wear can weaken rims and lead to falls and
serious accidents.
In particular, rims made of compos-
ite materials, such as carbon bre,
require special attention. Friction
caused by the rim brakes, but also by simply
riding the bike, puts a substantial amount of
strain on the bike.
• Only use brake pads that are designed for
use on the rims’ material.
• Each time before riding the bike, check for
wear, tear, defects, cracks and chipping on
the rims and wheels when they are made
of composite materials!
• If you nd any changes, do not ride the
bike with this part until a specialist retailer
or manufacturer has checked the part and
deemed it to be fully functional.
• Never expose components made of car-
bon bre to high temperatures. Intense
sunlight can produce high temperatures,
for example when the wheel has been
stored in a vehicle. This could damage the
component’s structure. Failing parts, falls
and very serious injuries could result.
You should also regularly check
your bicycle’s tyres. The minimum
and maximum permitted tyre pres-
sure is printed on the side of the tyres.
Please adhere to these levels, otherwise the
tyres could slip off the rims or explode! If the
ination pressure rating indicated on the tyre
and on the rim differ, the lower maximum
pressure and the higher minimum pressure
apply.
Example of tyre pressure information
30 – 80 PSI (2.25 – 5.5 BAR)
Tyres are wearable parts. You
should therefore regularly check the
pressure, tread and condition of
your tyres. Not ever tyre is designed for
every type of use. Allow a specialist retailer
to advise you when selecting tyres.
When replacing the original tyres or
the cranks, make sure that there is
enough free space between the
tyres and the shoe. Accidents and severe
falls could otherwise occur.
Your bicycle can only function safe-
ly and effectively if you replace
parts with suitable, authorised re-
placements. Please consult your manufac-
turer, importer or specialist retailer for ad-
vice on suitable replacement parts.
Only replace broken or worn key
parts with original replacement
parts from the manufacturer or parts
approved by your manufacturer. This is
mandatory in the case of light systems,
while the manufacturer’s warranty and/or
guarantee is usually nullied if you install
non-approved replacement parts.
