XVIII-3. Tires
Due to their function, bike tires are subject to wear. TTiis depends on how the bike is used and
the rider can influence this significantly.
Do not brake so sharply that the wheels lock.
•
Check the tire pressure regularly. The maximum permissible tire pressure, and normally
also the minimum permissible pressure, can be found on the tire wall.
• If necessary, inflate the tire up to the specified value. This reduces wear.
•
Do not expose frie tires to things that can damage them such as sunlight, petrol, oil, etc.
XVIII-4. Rims in conjunction with rim brakes
Owing to frie interaction of the rim brake with frie rim, not only the brake pad but also the rim is
subject to function related wear. If fine cracks appear or the rim flanges deform when the tire
pressure increases, this indicates increased wear. Wear indicators on the rim allow its wear con-
dition to be easily identified.
Check the wear condition of the rim at regular intervals.
XVIII-5. Brake pads
The brake pads on rim, roller, drum and disc brakes are subject to wear, the extent of which
depends on how the bike is used. If the bike is ridden in hilly regions, or use din a sporty man-
ner, the brake pads may need to be replaced more often. Check the wear condition of the pads
regularly and, If necessary, have them replaced by a professional bike workshop.
XVIII-6. Brake discs
Brake discs also wear out as a result of intensive braking, or during the course of time. Find out
from the manufacturer of your brakes or your specialist cycle shop about the respective wear
limits. You can have worn brake discs replaced at a professional bike workshop.
XVIII-7. Bike chains or toothed belts
The bike chain is subject to function-related wear the extent of which depends on care/mainte-
nance and how the bike is used (mileage, rain, dirt, salt, etc.).
•
To increase the service life of the bike, clean the bike chains and toothed belts regularly and
lubricate the chain.
•
Have the chain replaced by a professional bike workshop once rts wear limit has been
reached (20 "Bike chain").
XVIII-8. Chain rings, sprocket wheels and jockey wheels
In bikes with derailleur gears, the sprocket wheels, chain rings and jockey wheels are subject to
function-related wear. The extent of the wear depends on care/maintenance and how the bike is
used (mileage, rain, dirt, salt, etc.).
•
To increase the service life of the bike, you should clean and lubricate these parts regularly.
•
Have them replaced by a professional bike workshop once their wear limit has been
reached.
XVIII-9. Lamps of lighting set
Bulbs and other lamps are subject to function-related wear and therefore may need to be re-
placed.
•
In case you need to replace damaged bulbs, always carry spare ones with you.
