• UPPER LIMIT ADJUSTMENT
If the chain falls down from the biggest chainring - the chain guide is too far from the bike frame.
Turn the top adjustment bolt counterclockwise. Check the proper setting by shifting the chain on
all gears.
• FRONT DERAILLEUR TUNING
Any loose of the control cable should be eliminated by releasing the fixing screw of the cable and
stretching the cable (with pliers). Tighten the fixing screw. Check the functionality.
CHAIN
Chain transmits power from pedals to rear bicycle wheel. It is one of the most stressed parts of
bicycle therefore its maintainance requires higher attention. Rear derailleur provides correct chain
tension. Life of chain can be prolonged by periodical chain cleaning from mechanical dirt (e.g.
dust, mud). Oil with teflon is recommended for chain lubrication - your retailer will recommend
you appropriate lubricant. Chain links are sprawled by riding bicycle. Worn and damaged chain can
cause damages on cassette sprockets and chainwheels. If bicycle is used in hard terrain regularly
(e.g. wet and muddy) chain should be replaced by new one each 1000 km. Replace worn out chain
by new one of the same type and with the same amount of links like the worn out chain has.
BRAKE SYSTEM
Brake system consists of brake levers, cables, front and rear calipers, brake shoes, and is one of the
most important components of your bike. Right brake lever operates rear brake, left brake lever
operates front brake. Brakes are set by manufacturer. For your own safety do not make any brake
system adjustments until it is really necessary! Check periodically the wear of friction surfaces,
brake pads and keep rims clean. Untuned brake system has to be adjusted again or ask a special
bike service for help.
BRAKE CABLES
Brake system of bicycle will be effective only when brake cables are correctly stretched. Brake
cables can be set by adjusting screws on brake levers. Lubricate brake cables and outer casings with
oil which provides cables running smoothly. End cup should be placed on cable end to prevent its
ply apart and damage. Damaged or worn out cable must be replaced by new one.
BRAKE ADJUSTMENT
Brake shoes should be 1 mm from the rim in V-type brakes.
WARNING
Brake shoes may not touch the tire - otherwise this could cause an over-heating of the tire!
Check the wear, and if it is necessary, change them. Repleace worn out brake shoes with new
one original brake shoes matching your brake type.
