The crank arms must be seated tightly, otherwise the crank assembly may become
damaged.
➢
Since the crank arms can become loose, check the tightness of the
bottom bracket regularly.
➢
To check that the crank arms are seated tightly on the axles, shake
them regularly.
➢
If any play is found in the crank arms, have the bicycle checked and the
arms tightened by a dealer.
Using the gear shifter
Using the multispeed chain gear shifter
This operating manual describes the typical, conventional gear shift components of
an MTB, ATB, crossbike or racing cycle. In the case of differing components, refer to
the special information or attached manuals. If anything is unclear to you, consult
your bicycle dealer in the case of questions regarding assembly, maintenance and
operation.
Loose, worn, damaged or incorrectly adjusted gear shift components
represent a risk of injury to the rider.
Have the chain gear shifter adjusted by a dealer!
●
If the chain jumps off the chain sprockets, or
●
if abnormal noises are heard, or
●
if gear shifting does not work correctly, or
●
if the chain guide, derailleur or other gear shift components are loose,
damaged or bent, or
●
if the chain links are loose or worn, consult your dealer to have repairs
carried out.
The bicycle chain may not sit simultaneously on the smallest chain
sprocket at the front and the small outer sprocket at the rear, nor may it sit
simultaneously on the largest chain sprocket at the front and the large inner
sprocket at the rear, otherwise the chain may become disengaged.
Never pedal backwards when shifting gear, otherwise the gear shifter may be
damaged. Be careful when making adjustments to the gear shifter.
Due to incorrect adjustments, the chain may jump off the sprocket which may
lead to a fall. If you are not sure, have the work done by a dealer.
Do not ride without the spoke protector, otherwise the bicycle chain
or the gear shifter mechanism could get between the sprockets and the spokes.
Change to the lowest gear (largest rear sprocket) very carefully using the gear
shift, otherwise the changer mechanism could come into contact with the
spokes and damage them.
Shift lever operation
There are various types of gear shit levers.
The commonest types are described below.
Racing shift lever
The Shimano brake shift lever may exist in two versions.
