Dual Control Lever

For Hydraulic Disc Brake

IMPORTANT NOTICE

Contact the place of purchase or a bicycle dealer for information on installation

and adjustment of the products which are not found in the user's manual. A

dealer's manual for professional and experienced bicycle mechanics is available

on our website (https://si.shimano.com).

• Do not disassemble or alter this product.

For safety, be sure to read this user's manual thoroughly

before use, and follow it for correct use.

Important Safety Information

For replacement information, contact the place of purchase or a bicycle dealer.

WARNING

• This hydraulic brake system has different braking characteristics from those of the rim brake

type. Familiarize yourself sufficiently with the braking characteristics before use. 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, such

as when riding an electronic assist road bicycle or if the rider is heavy. If you feel that the

braking force is too high during the trial ride, stop using it and consult a place of purchase

or a distributor. Otherwise, you may lose control of the bicycle, fall, and be seriously injured.

- If you feel that the braking force is too low, stop using it and consult a place of purchase or

a distributor for the appropriate size of the disc brake rotor. Otherwise, you may lose

control of the bicycle, collide with something or fall, and be seriously injured.

• 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.

• The calipers and disc brake rotor will become hot when the brakes are operated, so do not

touch them while riding or immediately after dismounting from the bicycle, otherwise you

may get burned.

• Be careful not to allow any oil or grease to get onto the disc brake rotor and brake pads,

otherwise the brakes may not work correctly.

• If any oil or grease does get on the pads, you should consult a dealer or an agency. There is

the danger that the brakes may not work correctly.

• If noise occurs during brake operation, the pads may have been worn

down to the usable limit. Check that the brake system temperature has

been cooled down sufficiently, and then check that the thickness of

each pad is 0.5 mm or more. Or, consult a dealer or an agency.

• If the disc brake rotor is cracked or deformed, immediately stop using the brakes and consult

a dealer or an agency.

• If the disc brake rotor becomes worn down to a thickness of 1.5 mm, immediately stop using

the brakes and consult the place of purchase or a distributor. The disc brake rotor may break,

and you may fall off the bicycle. If using an ICE TECHNOLOGY disc brake rotor, immediately

stop use if the aluminum surface appears on one side.

• Vapor lock may occur if the brakes are applied continuously. To relieve this condition,

momentarily release the lever.

Vapor lock is a phenomenon in which the oil inside the brake system becomes heated,

which causes any water or air bubbles inside the brake system to expand. This can then

result in a sudden increase in the brake lever stroke.

User's manual

• The disc brake is not designed to work with the bicycle upside down. If the bicycle is turned

upside down or on its side, the brake may not work correctly, and a serious accident could

occur. Before riding the bicycle, be sure to operate the brake lever a few times to check that

the brakes operate normally. If the brakes do not operate normally, stop using the brakes

and consult a dealer or an agency.

• If you feel no resistance when depressing the brake lever, immediately stop using the brakes

and consult a dealer or an agency.

• If fluid leaks occur, immediately stop using the brakes and consult a dealer or an agency.

• It is important to completely understand the operation of your bicycle's brake system.

Improper use of your bicycle's brake system may result in a loss of control or a fall, which

could lead to severe injury. Because each bicycle may handle differently, be sure to learn the

proper braking technique (including brake lever pressure and bicycle control characteristics)

and operation of your bicycle. This can be done by consulting your professional bicycle dealer

and the bicycle's owners manual, and by practicing your riding and braking technique.

• If the front brake is applied too strongly, the wheel may lock and the bicycle may fall

forward, and serious injury may result.

• Always make sure that the front and rear brakes are working correctly before you ride the

bicycle.

• The required braking distance will be longer during wet weather. Reduce your speed and

apply the brakes early and gently.

• If the road surface is wet, the tires will skid more easily. If the tires skid, you may fall off the

bicycle. To avoid this, reduce your speed and apply the brakes early and gently.

• In the case of carbon levers, check before riding that there is no damage such as carbon

separation or cracking. If damage is found, do not use it; contact the place of purchase or a

bicycle dealer. Otherwise, the lever may break, and braking may become disabled.

• After reading the user's manual carefully, keep it in a safe place for later reference.

CAUTION

Cautions on the mineral oil

• Contact with eyes may result in irritation. 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 soap and water.

• Inhalation of mineral oil mist or vapors may cause nausea. Cover nose and mouth with a

respirator type mask and use in a well ventilated area. 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.

Burn-in period

• Disc brakes have a burn-in period, and the braking force will gradually increase as the

burn-in period progresses. Make sure that you are aware of any such increases in braking

force when using the brakes during the burn-in period. The same thing will happen when the

brake pads or disc brake rotor are replaced.

Notice:

• In the case of carbon levers, wash them by using a soft cloth. Be sure to use a neutral

detergent. Otherwise, the material may get damaged, and the strength may be affected.

• 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 should be

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 is normal.

If that happens, consult a dealer.

• Use soapy water or a dry cloth when carrying out cleaning and maintenance of the brake

system. Do not use commercially-available brake cleaners or silencing agents, as they can

cause damage to parts such as seals.

• Read the user's manuals for the front derailleur, rear derailleur, and brakes as well.

• 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 with the

following items, contact the place of purchase or a bicycle dealer.

• Is the brake oil leaking?

• Do the front and rear brakes work correctly?

• Is gear shifting carried out smoothly?

• Does each pad 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?

• Do any abnormal noises occur during operation?

• Can the seat post height be adjusted smoothly? (When using ST-RX810-LA)
