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 or a fall, which could lead to serious injury.

• 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.

• Use only the battery speciﬁed. Using an incorrect battery may cause

the battery to burst or leak ﬂuid, resulting in ﬁre, injury, or

defacement in the surrounding area.

• Do not use the battery outside its operating temperature ranges. If

the battery is used or stored in temperatures which are outside these

ranges, ﬁre, injury or problems with operation may occur.

• Do not throw or subject this product to strong shocks. If this is not

observed, bursting, overheating or problems with operation may

occur.

• Do not let grease adhere to the metal terminals. A conduction failure

may result.

• Do not use the battery if leakages, discoloration, deformation or any

other abnormalities occur. If this is not observed, bursting,

overheating or problems with operation may occur.

• If any leaked ﬂuid gets on your skin or clothes, wash it off

immediately with clean water. The leaked ﬂuid may damage your

skin.

• Store in a safe place out of the reach of small children to avoid letting

them swallow by mistake.

• Coin batteries are hazardous and must be kept away from

children. Never put batteries in mouth or in any part of

the body. Severe or fatal injuries can occur within 2 hours

if swallowed or placed inside the body. If this occurs or is

suspected, seek medical attention immediately.

• When operating the shifting switch, be careful not to allow your

ﬁngers to be caught in the derailleur. The powerful motor which

drives the electronic gear shifting derailleur will operate without

stopping until the shifting position is reached.

• 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.

• Riders must become accustomed to the higher performance of this

brake before riding the bicycle. Using larger diameter disc brake

rotors provides a higher braking force than smaller diameter disc

brake rotors. 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.

• 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.

• Be careful not to 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.

2 m m 0 . 5 m m

• 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.

• Do not use the brakes with ﬂuid leaking. Doing so may prevent the

brakes from operating and result in serious injury.

• 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 skid; to avoid this, reduce your

speed and apply the brakes early and gently. If the tires skid, you may

fall and be seriously injured.

• Do not use or leave the unit in hot and humid places such as where

the unit is exposed to direct sunlight, in a closed vehicle on a hot day,

or near a heater. If this is not observed, leakages of ﬂammable liquid

or gas, overheating or bursting may cause ﬁre, burns or other injury

to occur.

• Do not subject this product to extremely low air pressure. That may

result in an explosion of incorporated battery or the leakage of

ﬂammable liquid or gas from it. Transporting this product by air is not

a problem.

• Observe all federal, state and local environmental regulations when

disposing of this product, because it has a built-in battery in addition

to its button battery. Disposal of this product into ﬁre or a hot oven,

or mechanically crushing or cutting of it, can result in an explosion of

the built-in battery.

Built-in battery

CAUTION

Cautions on SHIMANO genuine mineral oil

• In the event of eye contact, ﬂush with fresh water and seek medical

assistance immediately.

Contact with eyes may result in irritation.

• In the event of skin contact, wash well with soap and water.

Contact with eyes may result in irritation.

• 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.

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

• To prevent noise and ensure the best performance, perform the

burn-in procedure after replacing the brake pads or disc brake rotor.

• Be sure to rotate the crank when carrying out switch operations which

are related to gear shifting.

• You can use E-TUBE PROJECT to update the software for the hood

button. Please contact your place of purchase for details.

• The components are designed to be fully waterproofed to withstand

wet weather riding conditions; however, do not deliberately place

them into water.

• Do not clean the bicycle with a high-pressure washer. If water gets

into any of the components, operating problems or rusting may result.

• Handle the components carefully, and avoid subjecting them to strong

shock.

• Be careful not to get water into the E-TUBE ports and the satellite

shifter connection port.

• Do not use thinners or strong solvents to clean the products. Such

substances may damage the surfaces.

• 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.

• 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 or 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.

• Contact the place of purchase for updates to the component software.

The most up-to-date information is available on the SHIMANO

website.

• Also read the manuals for other connected components together with

the manual for the brakes.

• Be sure to attach dummy plugs to any unused E-TUBE ports and the

satellite shifter connection port. If water gets into any of the

components, operating problems or rusting may result.

• The electric wire has small waterproof connectors, so do not

repeatedly connect and disconnect it too often. It may impair the

function.

About battery replacement

Before replacing the battery

• The included battery is for test purposes. When the battery level

becomes low, replace it with a new battery.

• When replacing the battery or opening/closing the battery holder,

move to an area well away from sources of water (such as rivers, lakes,

the ocean, or ditches).

• Do not perform this task in locations with a lot of water or mud, such

as outdoors during rain or car washing facilities. If this is not

observed, problems with operation may occur.

• Do not perform this task in areas with a lot of sand or dust in the air.

If this is not observed, problems with operation may occur.

• Before replacing the battery, wipe the battery holder and battery case

to remove water, dirt, etc. If this is not observed, problems with

operation may occur.

• Use your hands or an insulated tool with a blunt tip to perform this

task.

Using a conductive tool such as pliers may short the terminals of the

button battery and cause a malfunction.

• Take care of the terminals when removing the button battery in order

to prevent damage to the button battery.

• When performing this task with your hands, clean your hands and

remove all water and dirt before performing this task.

• Static electricity can damage electronic components. Discharge static

electricity from your body before performing this task.

Use one CR1632 battery for each of the left and right dual control

levers.

• It is recommended that you use a new battery.

Replacing the battery

1. Turn over the bracket cover from the front side.

2. Open the battery holder using a screwdriver, and remove the old

button battery by pushing its tip down.

If it is difﬁcult to remove the button battery, attach tape, etc. to the

surface of the button battery and pull it out.

Battery holder

3. Set the new battery to the battery holder. As shown in the ﬁgure, set

the battery with the positive (+) side showing.

Battery holder

4. Gently close the battery holder, and ﬁrmly secure it with a screwdriver.

Be careful not to overtighten as it may be damaged.

• Before closing the battery holder, check that the waterproof sealing

gasket and contacting surfaces are free of foreign substances (such as

dirt, dust, sand, hair, thread, or liquids).

• If there are foreign substances present, wipe them away with a clean,

dry cloth that does not shed lint or ﬁbers.

• Open the battery holder only when replacing the battery, and do not

leave it open. Doing so may cause problems with operation due to

foreign objects getting inside or deterioration to the electronic

component, etc.

• Make sure the battery is installed correctly. Installing the battery with

the positive (+) and negative (-) polarities reversed will not only stop

the component from operating, it may also cause the component to

malfunction.

• After replacement, check that it works normally.

Recovery function using wireless

function

If a problem occurs with wired communication for some reason when

riding using wired connections, it will automatically switch to wireless

communication.

However, it takes approximately 10 seconds to switch to wireless

communication.

* Wireless communication with the rear derailleur must have been

enabled by conﬁguring the settings in advance. Contact the place of

purchase for details.

Method for pairing with the rear

derailleur

Refer to the user's manual for E-TUBE PROJECT or contact the place of

purchase for information about pairing.

How to perform burn-in

To optimize the performance of the brake pads and disc brake rotor,

perform the burn-in procedure as explained in the steps below.

1. Ride your bicycle in a ﬂat and safe area without obstacles and

accelerate to a moderate speed.

2. Operate the brake lever until you slow down to walking speed.

Do this only with one brake lever at a time. Be careful when

performing this procedure. Always operate your brake lever with

moderation, especially when you burn in the front brake.

3. Repeat steps 1 and 2 for at least 20 times for both the front and rear

brakes. While repeating the process, the brake force will increase.
