prevent personal injury and physical damage to equipment and
surroundings. The instructions are classified according to the degree of
danger or damage which may occur if the product is used incorrectly.
DANGER

to equipment and surroundings.
Important safety information
WARNING
•
Because each bicycle may handle slightly differently depending on the
model, be sure to learn the proper braking technique (including brake
lever pressure and bicycle control characteristics) and operation of your
bicycle. Improper use of your bicycle's brake system may result in a loss
of control, which could lead to serious injury due to a fall or collision.
•
Do not disassemble or modify the product. This may cause the product
to not operate correctly, and you may suddenly fall and be seriously
injured.
•
This hydraulic brake system has different braking characteristics from
those of the rim brake type, demonstrating relatively high braking force
at the beginning of braking (higher than the rim brake type);
familiarize yourself sufficiently with the braking characteristics before
using it. If you ride the bicycle without becoming sufficiently familiar
with the braking characteristics, braking may cause you to fall off the
bicycle, potentially causing serious injury or a fatal accident.
•
The braking force for a hydraulic brake system will increase along with
the size of the disc brake rotor (140 mm, 160 mm, 180 mm, 203 mm).
–Do not use a 203 mm disc brake rotor. This will excessively increase
the braking force, which could cause you to lose control of the
bicycle, fall, and be seriously injured.
–Only use a 180 mm disc brake rotor if you are unable to obtain
sufficient braking force with a 160 mm disc brake rotor upon a trial
ride, such as when riding an electronic assist road bicycle or if the
rider is heavy. Otherwise, you may lose control of the bicycle, fall,
and be seriously injured.
–If you feel that the braking force is too high or too low, stop use and
consult a place of purchase or a distributor. Accidents or falls may
occur due to losing control of the bicycle, possibly resulting in serious
injury.
•
Please use extra caution to keep your fingers away
from the rotating disc brake rotor. The disc brake
rotor is sharp enough to inflict severe injury to your
fingers if caught within the openings of moving
rotor.
•
Do not touch the calipers or disc brake rotor while riding or
immediately after dismounting from the bicycle. The calipers and disc
brake rotor will become hot when the brakes are operated, so you may
get burned if you touch them.
•
Do not allow any oil or grease to get onto the disc brake rotor and
brake pads. Riding the bicycle with oil or grease on the disc brake rotor
and brake pads may prevent the brakes from operating and result in
serious injury due to a fall or collision.
•
Check the thickness of the brake pads and do not use them if they have
a thickness of 0.5 mm or less. Doing so may prevent the brakes from
operating and result in serious injury due to a fall or collision.

•
Do not use the disc brake rotor if it is cracked or deformed. The disc
brake rotor may break, and result in serious injury due to a fall.
•
Do not use the disc brake rotor if its thickness is 1.5 mm or less. Also do
not use it if the aluminum surface becomes visible. The disc brake rotor
may break, and result in serious injury due to a fall.
•
Do not continuously apply the brakes. Doing so may cause a sudden
increase in the brake lever stroke, preventing the brakes from operating
and resulting in serious injury due to a fall or collision.
•
Do not use the brakes with oil leaking. Doing so may prevent the brakes
from operating and result in serious injury due to a fall or collision.
•
Do not apply the front brake too strongly. If you do so, the front wheel
may lock and the bicycle may fall forward, and serious injury may result.
•
Because the required braking distance will be longer during wet
weather, reduce your speed and apply the brakes early and gently. You
may fall or collide and be seriously injured.
•
A wet road surface may cause tires to lose traction; therefore, to avoid
this, reduce your speed and apply the brakes early and gently. If the
tires lose traction, you may fall and be seriously injured.
CAUTION
Cautions on SHIMANO genuine mineral oil
•
In the event of eye contact, flush with fresh water and seek medical
assistance immediately. Contact with skin may cause a rash and
discomfort.
•
In the event of skin contact, wash well with soapy water. Contact with
skin may cause a rash and discomfort.
•
Cover nose and mouth with a respirator type mask and use in a well
ventilated area. Inhalation of mineral oil mist or vapors may cause
nausea.
•
If mineral oil mist or vapor is inhaled, go immediately to an area with
fresh air. Cover up with a blanket. Stay warm and stable and seek
professional medical advice.
Bed-in period
•
Disc brakes have a bed-in period, and the braking force will gradually
increase as the bed-in period progresses. Accidents or falls may occur
due to losing control of the bicycle, possibly resulting in serious injury.
The same thing will happen when the brake pads or disc brake rotor
are replaced.
Notice
•
To prevent noise and ensure the best performance, perform the bed-in
procedure after replacing the brake pads or disc brake rotor.
•
In the case of carbon levers, wash them with a soft cloth using a neutral
detergent. Otherwise, the material may be damaged and lose strength.
•
Avoid leaving the carbon levers in places where high temperatures are
present. Also keep them well away from fire.
•
Be sure to keep turning the crank during the lever operation.
•
When the bicycle wheel has been removed, it is recommended that pad
spacers are installed. Do not depress the brake lever while the wheel is
removed. If the brake lever is depressed without the pad spacers
installed, the pistons will protrude further than normal. If that happens,
consult a place of purchase.
•
Use soapy water and a dry cloth when cleaning and carrying out
maintenance of the brake system. Do not use commercially available
brake cleaners or silencing agents. Such substances can cause damage
to parts such as seals.
•
Also read the user's manuals for the front derailleur, rear derailleur,
and brake.
•
Products are not guaranteed against natural wear and deterioration
from normal use and aging.
•
For maximum performance we highly recommend SHIMANO lubricants
and maintenance products.
•
When using ST-RX810-LA, before riding the bicycle, confirm that the
seat height will not impair the operation of the bicycle (even if the seat
height has been adjusted within the adjustment range).
Regular inspections before riding the bicycle
Before riding the bicycle, check the following items. If any problems are
found, consult your place of purchase or a distributor.
•
Are there any signs of brake oil leakage?
•
Do the front and rear brakes work correctly?
•
Is gear shifting carried out smoothly?
•
Do the pads have a thickness of 0.5 mm or more?
•
Is the disc brake rotor cracked or deformed?
•
Are the levers securely installed to the handlebar?
•
Are there signs of cracks or peeling on the levers?
•
Do any abnormal noises occur during operation?
•
Can the seat post height be adjusted smoothly? (When using ST-RX810-
LA)

Caution on operation
After gear shifting is completed, both levers A and B return to their initial
position.
Do not push levers A and B at the same time. Gear shifting is not
performed if the levers are pushed at the same time.
* Some models have two-step gear shifting.
