Warning:
In order that the gear system functions correctly and
not to shorten the lifespan of its parts (chain,
freewheel, pedals):
• Avoid heavy, aggressive gear changes.
• Avoid crossing the chain (by using the large cog and
the large chain ring or the small cog and the small
chain ring)
• If the chain is crossed (Diagram 2), it may be in contact
with the front derailleur.
Warning to users:
Bicycles with brakes which connect the surface of the rim to the braking system are subject to wear of
the rim wall at the braking surface, as a result of the braking forces and the friction suffered by the rim
at this surface.
We recommend that users pay particular attention to this wear, because a reduction in the thickness
of the rim wall can cause tyre maintenance defects and injury.
Regularly check that the internal and external surfaces of the rims show no signs of cracking or wear.
Do not use wheels showing signs of advanced wear of the rim's braking surface.
IMPORTANT : This safety procedure is difficult, so it is better to contact one of our technical workshops to
carry out this type of procedure. Nevertheless, here are a few pointers for users who wish to carry out the
procedure themselves.
NB: For disk brakes, please refer to the manufacturer’s manual.
Replacing brake pads.
1/ Open the calipers.
2/ Remove the pad using a suitable spanner (Allen key or flat key depending on the model).
3/ Replace the pad, being careful to follow the assembly sequence of washers and spacers carefully.
4/ Tighten up the pad using a suitable spanner, using a tightening torque of between 6 and 9 Nm.
NB: some pads have a mounting direction: the arrow should face the wheel’s rotation direction when the bicycle is
moving forwards.
Replacing disk brake pads:
Replace the worn parts with the correct replacement parts obtained from qualified sources.
Remplacer les freins à tambour :
Replace the worn parts with the correct replacement parts obtained from qualified sources.
Rim wear:
Changing gear: continue to pedal but not too hard, and move the gear shifter (lever or rotating shifter) until the
chain is in place on the selected chain ring or cog. Each position of the shifter corresponds to a chain position on the
cogs.
•
If the chain does not move up onto the cog: you can try "overshifting" by pushing the lever slightly beyond position
without moving it into the next position.
=> If this does not work: you will need to adjust the cable tension (cf. chapter “adjusting the gear system”).
•
If the chain does not move down quickly, see the chapter entitled “adjusting the gear system”. The chain should
move smoothly between cogs.
