WARNING: Always check the brake
cable routing to ensure smooth and
free application of the brakes. Cables
that are kinked, frayed or otherwise
damaged, or cables that are wrapped
around the stem or frame may affect
braking power or cause unintended
sudden stops and loss of control.
Dérailleur systems
All the pivoting points of the rear dérailleur should be
lubricated with light oil at least every month. Be sure
to wipe off any excess oil to avoid attracting dirt into
the mechanisms. The shifting cables should be cleaned
and re-coated with a thin layer of grease every six
months, or whenever new cables are being installed.
Pre-stretch the dérailleur cables to remove slack (see
figure).
Dérailleur inspection:
• Check the dérailleur system every month.
• The rear dérailleur should shift the chain cleanly from
one clog to the next without hesitation.
• Since this bicycle is equipped with an Index System,
check if each notched position in the shifter equates
to a new gear position.
• Check and make sure that the rear dérailleur does not
rub the chain after shifting.
• The dérailleur should never cause the chain to fall off
the inner or outer freewheel cogs. The chain should
not fall off the chain ring at any time.
• Dérailleur control cables are critical components and
must be well-maintained for accurate shifting perfor-
mance. Check the cables for any sign of rust, fraying,
kinks, broken strands, and any damage to the cable
housing. Replace damaged cables immediately be-
fore you ride.
