FRONT DERAILLEUR
Front deraileur is controlled by left shifting lever (left shifting grip). It changes the transmission
ratio by moving the chain to different chainrings. For proper functionality, the chain guide must be
positioned paralely with chainrings. The control cable must be stretched. During an operation, there
is a possibility that the control cable can be released, and the front deraileur system can get mistuned.
• LOWER LIMIT SET UP
If the chain falls down from the smallest chainring - the chain guide is too close to the bike frame.
Turn the lower limit set up bolt clockwise.
• UPPER LIMIT SET UP
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 bolt of the cable and
stretching the cable (with pliers). Tighten the fixing bolt. 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.
Correct chain tension on bicycles without rear derailleur is provided by rear wheel displacement in
fork. 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.
BRAKE SYSTEM
Brake system consists of brake levers, cables, front and rear calipers, brake pads, and is one of the most
important components of your bike. Right brake lever operates rear brake, left brake lever operates front
brake. Bicycle equipped by coaster brake can be stopped by pushing on pedal backwards against
direction of ride. Brakes are set up by manufacturer, so for your own safety do not make any adjustments,
until it is really necessary! Check periodically the wear of friction surfaces, brake pads and keep rims
clean. When brake system is mistuned, you have to set it up, or ask a special bike service for help.
