WARNING
• Do not press the FLIGHT DECK (cycle computer)
switch while riding, otherwise you might lose control
of your bicycle and have an accident. Stop the
bicycle before operating any of the switch.
• Do not pay excessive attention to the computer
data while riding, otherwise you might have an
accident.
• Do not disassemble the front suspension fork,
otherwise the outer tube and the inner tube will
come apart and serious injury may result.
• Use tires with an outside circumference of less than
690 mm (for the FS-C810) or 725
mm (for the FS-C812) so that the
tire does not touch the bridge
of the front suspension fork. If a
fender has been fitted, make
sure that the tire does not touch
the fender when the tire is
installed.
• Install the handlebar and the handlebar stem
correctly while referring to the Service Instructions
for these parts. If they are not installed correctly,
you might lose control of your bicycle and have an
accident.
• The FS-C810 does not include a hanger on the front
suspension fork, and so only cantilever brakes that
are designed to be installed to the front suspension
fork without a hanger can be used.
• Only disc brakes can be installed to the FS-C812 front
suspension.
• Keep used batteries out of the reach of children, and
dispose of them in accordance with local waste
regulations. If batteries are swallowed by mistake,
seek medical advice immediately.
• Use a neutral detergent to clean the chain. Do not
use alkaline or acidic detergents that are designed to
remove things such as rust, as they can damage the
chain and cause the chain to break.
• When removing the rear wheel, disconnect the cable
from the rear hub and then place the chain onto the
top (smallest sprocket) of the cassette sprocket first.
Make sure the rotor
temperature has decreased
sufficiently when removing
the cord if the disc brake is
mounted. Touching the rotor
immediately after riding the
bicycle may result in burns.
• Obtain and read the service instructions carefully
prior to installing the parts. Loose, worn, or
damaged parts may cause serious injury to the rider.
We strongly recommend only using genuine Shimano
replacement parts.
• Check that the wheels are fastened securely before
riding the bicycle. If the wheels are loose in any way,
they may come off the bicycle and serious injury may
result.
• Read these Technical Service Instructions carefully,
and keep them in a safe place for later reference.
Note
• The front derailleur shifts gears by the operation of
the manual shift switches, regardless of whether the
mode setting is automatic or manual. However, the
rear derailleur will not shift gear in automatic mode,
even when the manual shift switches are operated.
• When sufficient power is not being generated at
times such as immediately after starting to ride,
movement of derailleurs and suspension may be
limited and the system may not accept operator
instructions.
Refer to the explanations of other functions for
details.
• Turn the pedals when carrying out both front and
rear gear shifting.
• Do not turn the pedals backward.
• Do not clean the bicycle with high-pressure sprays. If
moisture gets into the components, it may cause
operating problems or rust.
• Do not disassemble any of the units, otherwise they
may not operate correctly.
• A beep will sound when gear shifting occurs.
• The various units are designed to be water-resistant
so that they can be used for riding in wet weather.
However, they should not be immersed in water.
• Do not leave the FLIGHT DECK exposed to extremely
hot weather, and do not subject it to shocks.
• To clean the units, wipe with a dry cloth or a cloth
that is lightly moistened with neutral detergent.
Substances such as thinner will damage the unit
surfaces.
• Roughly 1 minute after stopping the bicycle, the
energy saving function is activated and the liquid
crystal display turns off. The backlight turns off
about 5 seconds after stopping the bicycle.
• Parts are not guaranteed against natural wear or
deterioration resulting from normal use.
• For any questions regarding methods of handling or
maintenance, please contact the place of purchase.
For safety, be sure to read these instructions,
and follow them for correct use.

What is automatic shifting mode?
This is a riding mode in which the gears are selected automatically
according to the riding speed.
The rotation of this bicycle’s free hub generates power
used to switch gears and control the suspension.
What is manual shifting mode?
This is a riding mode in which the gears are selected according to the preferences of the rider.
In order to get better results in automatic mode
The shifting points can be changed to any one of five different points both before
and after the standard shifting points. You can change the settings to find the
shifting points that best suit your preferences. (Page 10)
