electric shocks or short-circuits may occur.

Brake

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 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.

Hydraulic disc brake

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.

For installation to the bicycle and maintenance

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 fluid leaking. Doing so may prevent the brakes from operating and result in

serious injury due to a fall or collision.

When operating the shift switch, be careful not to allow your fingers to be caught in the derailleur. The motor

in the derailleur is powerful enough to be operated without stopping until the shifting position is reached,

and may cause serious injury if your fingers interfere with the shifting motion.

Hydraulic disc brake

Please make sure to keep your fingers away from the rotating disc brake rotor during installation or

maintenance of the wheel. The disc brake rotor is sharp enough to inflict severe injury to your fingers if

caught within the openings of moving rotor.

Do not use the disc brake rotor if it is cracked or warped. 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. Replace the disc

brake rotor with a new one.

The calipers and disc brake rotor will become hot when the brakes are operated; do not touch them while

riding or immediately after dismounting from the bicycle. Otherwise, you may get burned.

Do not use oil other than SHIMANO genuine mineral oil. Doing so may prevent the brakes from operating and

result in serious injury due to a fall or collision.

Use only mineral oil from a container that has been stored in a clean and sealed state. Doing so may prevent

the brakes from operating and result in serious injury due to a fall or collision.

Do not let water or air bubbles get into the brake system. Doing so may prevent the brakes from operating

and result in serious injury due to a fall or collision.

If the quick release lever is on the same side as the disc brake rotor, confirm that it does not interfere with the

disc brake rotor. Otherwise, the bicycle may fall forward, and serious injury may result.

Do not use with a tandem bicycle. Doing so may prevent the brakes from operating and result in serious injury

due to a fall or collision.

When installing the brake caliper using screw fixing pins, be sure to use fixing screws of the appropriate

length.

If not, the screw fixing pins may not be securely fastened, and the screws may fall out.

Brake hose

The connector insert is for this brake hose only. Use an appropriate connector insert according to the

following table. Use of a connector insert incompatible with the brake hose may cause fluid leaks.

Be sure to also inform users of the following:

Be sure to rotate the crank arm when carrying out any operations which are related to gear shifting.

The connectors are small and waterproof, so do not connect and disconnect electric wires except when

necessary. Doing so may impair the waterproofing.

Be careful not to get water into the E-TUBE ports.

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.

Be sure to keep rotating the crank arm during gear shifting operations.

Handle the components carefully, and avoid subjecting them to strong shock.

Do not use the thinners or harsh solvents to clean the products. Such substances may damage the surface.

If gear shifting operation does not feel smooth, consult the place of purchase for assistance.

Keep away from magnetic objects. If this is not observed, problems with operation may occur.

When installing a product that uses a magnet, make sure the magnet is set in the specified location before

installing the product.

Contact the place of purchase for updates of the component software. The most up-to-date information is

available on the SHIMANO website.

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.

Lithium-ion battery

Lithium-ion batteries are recyclable, valuable resources.

For information on used batteries, contact the place of purchase or a distributor.

Charging can be carried out at any time regardless of the battery level. Always be sure to use the special

battery charger to charge the battery until it is fully recharged.

The battery is not fully charged at the time of purchase. Before riding, be sure to fully charge the battery.

When the battery is completely depleted, charge it as soon as possible. If you leave the battery without

charging it, it will cause the battery to deteriorate.

The battery is an exhaustible item. The battery will gradually lose its capacity to charging after repeated use. If

the length of time that the battery can be used becomes extremely short, it has probably reached the end of

its life, and so you will need to purchase a new battery.

The life of the battery will vary depending on factors such as the storage method, the usage conditions, the

surrounding environment and the characteristics of the individual battery pack.

If storing the battery away for a long period, remove it when the battery level is 50% or higher or when the

green indicator is illuminating in order to prolong its useful life. It is recommended that you charge the

battery every six months.

If the storage temperature is too high, the performance of the battery is reduced, and its useable time will be

shorter. When you use the battery after a long storage period, store the battery indoors where the battery

will not be exposed to direct sunlight or rain.

If the ambient temperature is too low, the battery's usable time will be shorter.

When storing the battery away, remove the battery from the bicycle and install the terminal cover first.

The charging time is approximately 1.5 hours. (Note that the actual time will vary depending on the remaining

battery charge.)

If the battery feels difficult to insert or remove, apply specified grease (Premium Grease) to the part that

touches the O-ring at the side.

After removing the battery from the bicycle for storage, install a dummy plug to each port.

The charging time of an AC adapter with a USB port is about 1.5 hours, and that of computer USB port type

about 3 hours. (Note that the actual time will vary depending on the amount of charge remaining in the

battery. Depending on the specifications of the AC adapter, recharging via the AC adapter may require as

much time (about 3 hours) as recharging via PC.)

If this is not done, the units may not operate correctly.

Check the procedures which are given in the user's manual for the E-TUBE PROJECT when connecting and

disconnecting units.

The tightness of the PC link cable will tend to drop after repeated connections and disconnections. If this

happens, replace the cable.

Do not connect two or more PC linkage devices at the same time. If two or more PC linkage device units are

connected, they will not operate correctly. In addition, the PC may need to be restarted if operating errors

occur.

PC linkage devices cannot be used while the battery charger is connected.

Rear derailleur

If gear shifting operation does not feel smooth, consult the place of purchase for assistance.

If you feel the chain or other drivetrain components skipping, consult the place of purchase for assistance.

If the pulleys of the derailleur develop excess play or noise, consult the place of purchase for assistance.

The gears should be periodically washed with a neutral detergent. In addition, cleaning the chain with neutral

detergent and lubricating it can be an effective way of extending the life of the gears and the chain.

Hydraulic disc brake

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.

Be sure to attach dummy plugs to any unused E-TUBE ports.

Be sure to use SHIMANO original tool TL-EW02 to remove the electric wires.

Contact SHIMANO INC. for information regarding the shipment of the battery charger to South Korea and

Malaysia.

Use a brake hose/outer casing which still has some length to spare even when the handlebars are turned all

the way to either side. Furthermore, check that the dual control levers do not touch the bicycle frame when

TO ENSURE SAFETY

19

the handlebars are turned all the way.

The clamp band, clamp bolt and clamp nut are not compatible with other products. Be sure to always use the

clamp band, clamp bolt and clamp nut which is specific to each product.

Electric wires/electric wire covers

Secure the electric wires with a zip tie so that they do not interfere with the chainrings, sprockets or tires.

The strength of the adhesive is fairly weak to prevent the paint on the frame from being peeled off at when

removing the electric wire cover, such as when replacing the electric wires. If the electric wire cover is peeled

off, replace it with a new one. When removing the electric wire cover, do not peel it off too vigorously. If so,

the paint on the frame will peel off, too.

Do not remove the wire holders which are attached to the built-in type electric wires (EW-SD50-I). The wire

holders prevent the electric wires from moving inside the frame.

When installing to the bicycle, do not forcibly bend the electric wire plug. It may result in a poor connection.

Rear derailleur

Be sure to adjust the high limit screw and the low limit screw according to the instructions given in the

adjustment section.

If these are not adjusted, the chain may become clamped between the spokes and the largest sprocket and

the wheel may lock, or the chain may slip onto the small sprocket.

Periodically clean the shifting unit and lubricate all moving parts (mechanism and pulleys).

If gear shifting adjustments cannot be carried out, check the degree of parallelism of the dropout.

The guide pulley and tension pulley have an arrow on one side to indicate the direction of rotation. When

installing the pulleys, install so that the surfaces with arrows are on the inner side when looking from the

outer side of the shifting unit.

Hydraulic disc brake

If the brake caliper mounting boss and the dropout are not of standard dimensions, the disc brake rotor and

caliper may touch.

When the bicycle wheel has been removed, it is recommended that pad spacers are installed. The pad spacers

will prevent the piston from coming out if the brake lever is depressed while the wheel is removed.

If the brake lever is depressed without the pad spacers installed, the pistons will protrude further than normal.

Use a slotted screwdriver or other tool to push open the brake pads, while being careful not to damage the

surfaces of the brake pads. (If the brake pads are not installed, use a flat-shaped tool to push the pistons

straight back in, while being careful not to damage them.)

If it is difficult to push the brake pads or pistons back, remove the bleed screws and try again. (Note that some

oil may overflow from the reservoir tank at this time.)

TO ENSURE SAFETY

20

The actual product may differ from the illustration because this manual is

intended mainly to explain the procedures for using the product. For installation to the bicycle

Be sure to also inform users of the following:

In the case of using SM-BTR1

Use isopropyl alcohol, 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.

If the disc brake rotor is worn, cracked or warped, it should be replaced.

Dual control lever

Dummy plugs are installed at the time of shipment from the factory. Do not remove them except when

necessary.

When routing the electric wires, take care to ensure that they do not interfere with the brake levers.

Notes on reinstalling and replacing components

When the product is reinstalled or replaced, it is automatically recognized by the system to allow operation

according to the settings.

If the system does not operate after reassembly and replacement, follow the system power reset procedure

below to check the operation.

If the component configuration changes or malfunction is observed, use the E-TUBE PROJECT software to

update the firmware of each component to the latest version and perform a check again. Also make sure that

the E-TUBE PROJECT software is the latest version. If the software is not the latest version, the component

compatibility or the product functions may not be available.

About used batteries

Lithium-ion batteries are recyclable, valuable resources.

For information on used batteries, contact the place of purchase or a distributor.

About system power reset

When the system fails to operate, it may be recovered by resetting the system power.

After the battery is removed, about one minute is usually required for the system power to reset.

Remove the battery from the battery mount. After about one minute, install the battery.

TO ENSURE SAFETY

If using SM-BTR2/BT-DN110/BT-DN110-A

About compatibility with E-TUBE

Disconnect the plug from SM-BTR2/BT-DN110/BT-DN110-A. After about one minute, insert the plug.

Connection and communication with PC

PC linkage devices can be used to connect a PC to the bicycle (system or components), and E-TUBE PROJECT

can be used to carry out tasks such as customizing single components or the whole system and updating their

firmware.

If your versions of E-TUBE PROJECT software and firmware for each component are not up to date, there

could be problems operating the bicycle. Check the software version and update it to the latest one.

Connection and communication with smartphone or tablet

E-TUBE PROJECT for smartphones/tablets can be used to carry out tasks such as updating firmware and

customizing single components or the whole system, after connecting the bicycle (system or components) to a

smartphone or tablet via Bluetooth LE.

E-TUBE PROJECT: Application for smartphones/tablets

Firmware: Software inside each component

Disconnect the Bluetooth LE connection when not using E-TUBE PROJECT for smartphones/tablets.

Using a wireless unit without disconnecting the Bluetooth LE connection could increase battery consumption.

About the multi-shifting function

Connecting this system to E-TUBE PROJECT and switching [Multi shift] to [ON] will allow you to continuously

shift gears while the shift switch is held down. When modifying this setting, carefully read Items

configurable in E-TUBE PROJECT in this dealer's manual.

Gear-shifting interval

[Gear-shifting interval] can be set to one of five levels as a multi-shifting function setting in E-TUBE PROJECT:

[Very fast], [Fast], [Normal], [Slow], or [Very slow] (Default: [Normal]).

TO ENSURE SAFETY

22

A faster [Gear-shifting interval] setting will result in faster gear shifting. The rider can quickly adjust the

traveling speed and the speed at which the crankset turns (cadence below) in response to changes in riding

conditions.

However, if a gear shifting operation is performed at an insufficient cadence when the system is set to a fast

gear-shifting interval, the chain may be unable to follow the movement of the rear derailleur, resulting in the

following problems:

The chain may slip over the tip of the cassette sprocket teeth

The cassette sprocket may deform

The chain may break

Fully understand the features of the gear-shifting interval, then set the gear-shifting interval according to the

riding conditions, such as the terrain and the riding style of the rider.

Gear-shifting interval Benefits Drawbacks

Fast setting

Slow setting

Quick multi-shifting is possible

The rider can quickly adjust the cadence or

traveling speed in response to changes in the

riding conditions

A high cadence is required when gear shifting

Unintended over-shifting occurs easily

Gear shifting can be performed reliably Gear shifting takes some time

How to operate Gear position control [Gear position control] in this system is set to [Yes] by default. Therefore, if you try to shift into gear positions

that would lower the chain tension, shift switches may shift differently from the basic operations.

The figure below shows the gear positions that would lower the chain tension and the shifting operations

performed when you shift into those gears.

Points to remember when shifting the front derailleur

When you shift the front into the smallest chainring, shifting is controlled as follows.

Gear position control (during front gear shifting)

Gear position in the rear When the front is shifted into the smallest chainring

Smallest or 2nd smallest sprocket
