9�4 Gearshift system

after some time.
If an accident or other event causes problems with the gearshift system, it must
be repaired or readjusted by a specialist

9�5 Brakes
WARNING
Only have repairs and adjustments to brakes carried out by qualified personnel.
Brake discs and brake pads are wear parts, which means they need to be inspected regularly
(see Section 10 on page 55). The brakes must always be checked or serviced by a specialist if:
the brake pads are thinner than 0.5 mm
(see figure)
the brake lever touches the handlebar when
braking
the braking power decreases
the brakes squeak or vibrate
the brakes exhibit a variable pressure point
CAUTION
Brake pads must not come into contact with oil or grease.
TIP
We recommend having hydraulic brake systems serviced every two to three years.
The interval depends on how often the bike is used, but keep in mind that brake fluid
will age even if the bike is not used often.

9�8 Spokes and wheels

concentricity of the wheel. Check the spokes regularly for damage and sufficiently high spoke
tension or have them checked by a specialist.
Have damaged spokes repaired or replaced by a specialist if necessary
If a wheel exhibits excessive lateral or radial runout, have it repaired or centred
by a specialist
