Gear combinations
noTiCe
The use of incorrect gear combinations can damage the
gear shift system.
Risk of damage!
• Do not combine the small chainring with the smallest
rear sprocket or the large chainring with the largest rear
sprocket.
Only certain chain ring combinations or gears are deemed appro-
priate for correct usage of the bicycle
(see Fig.
“Appropriate gear combinations”
).

Incorrect gear combinations cause the chain to skew, leading to
increased wear to chain rings, sprockets and the chain
•
Use the gear combinations in such a way that the chain
remains parallel to the direction you are riding in as far as
possible.
•
If you are at all unsure, ask your specialist dealer to show you
how to use the derailleur gears.
7.1.1.2
Checking the chain tension
For bicycles with derailleur gears, the chain is tensioned by the
chain guide with the guide rollers in the rear derailleur.
1.
Check to see if the chain is starting to sag (visual check).
2. Gently push the chain guide towards the front and then
check to see if it falls back into position by itself.
•
If the chain is sagging or if the chain guide does not repo-
sition itself, you should ask your specialist dealer to repair
the rear derailleur system.
