TO ENSURE SAFETY
About the multi-shifting function
• Connecting this system to E-TUBE PROJECT and switching [Multi shift mode setting] to
[ON] will allow you to continuously shift gears while the shifting 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]).
• 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 front chainwheel 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, and then set the gear-shifting
interval according to the riding conditions, such as the terrain and the riding style of the
rider.

Brake
• Each bicycle may handle slightly differently depending on the model. Therefore, 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 severe injury. For proper
operation, consult a professional bicycle dealer or the bicycle's owner's manual. It is also
important to practice riding and braking, etc.
• If the front brake is applied too strongly, the front 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 riding the
bicycle.
• The required braking distance will be longer during wet weather. Reduce your speed and
apply the brakes early and gently.
11
TO ENSURE SAFETY
• If the road surface is wet, the tires will skid more easily. If the tires skid, you may fall off
the bicycle; therefore, to avoid this, reduce your speed and apply the brakes early and
gently.
Hydraulic disc brake
• Please make sure 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 in
the openings of the disc brake rotor while it is moving.
• 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.
• 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 brake pads, you should consult a place of purchase or
a distributor. Otherwise, the brakes may not work correctly.
• If noise occurs during brake operation, the brake pads may
0.5 mm2 mm
have been worn down to the usable limit. Check that the
brake system temperature has cooled down sufficiently,
and then check the thickness of the brake pad. If the
thickness is 0.5 mm or less, the brake pad needs to be
replaced with a new one. Consult a place of purchase or a
distributor.
• If the disc brake rotor is cracked or deformed, immediately stop using the brakes and
consult a place of purchase or a distributor.
• If the disc brake rotor becomes worn down to a thickness of 1.5 mm or less, or if the
aluminum surface appears, immediately stop using the brakes and consult a place of
purchase or a distributor. The disc brake rotor may break, and you may fall off the
bicycle.
• Vapor lock may occur if the brakes are applied continuously; therefore, please refrain
from doing this.
Vapor lock occurs when the oil inside the brake system becomes heated, which causes
the water or air bubbles inside the brake system to expand. This can then result in a
sudden increase in the brake lever stroke.
• The disc brake is not designed to work when the bicycle is 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 depress 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 place of purchase or a distributor.
12
TO ENSURE SAFETY
• If you feel no resistance when depressing the brake lever, immediately stop using the
brakes and consult a place of purchase or a distributor.
• If fluid leaks occur, immediately stop using the brakes and consult a place of purchase or
a distributor.
For installation to the bicycle, and maintenance:
• When the shifting switch is operated, the powerful motor which drives the front
derailleur will operate to the shifting position without stopping, so be careful not to get
your fingers caught.
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 in
the openings of the disc brake rotor while it is moving.
• If the disc brake rotor is cracked or warped, be sure to replace the disc brake rotor with a
new one.
• If the disc brake rotor becomes worn down to a thickness of 1.5 mm or if the aluminum
surface becomes visible on one side, be sure to replace the disc brake rotor with a new
one.
• Check that the brake system has cooled down sufficiently before attempting brake
system maintenance.
• Use only SHIMANO genuine mineral oil. If other types of oil are used, it may cause
problems with brake operation, and cause vapor lock or the brake system to be unusable
• Be sure to use only oil from a freshly-opened container, and do not re-use oil which has
been drained from the bleed nipple. Old or reused oil may contain water, which could
cause vapor lock in the brake system.
• Be careful not to let water or air bubbles get into the brake system. Otherwise, vapor
lock may occur. Be particularly careful when removing the cover of the reservoir tank.
• If cutting the hose in order to adjust the length of the brake hose, or when changing
over the brake hose from left to right or vice versa, be sure to bleed the air from the
hose according to the steps in "Adding mineral oil and bleeding air".
13
TO ENSURE SAFETY
• When turning the bicycle upside down or on its side, the brake system may have some air
bubbles inside the reservoir tank which are still there when the bleed screw is closed, or
which accumulate in various parts of the brake system when it is used for long periods.
This disc brake system is not designed to work with the bicycle upside down. If the bicycle
is turned upside down or on its side, any air bubbles inside the reservoir tank may move
in the direction of the calipers and if the bicycle is ridden in this condition, there is a
danger that the brakes may not operate and a serious accident could occur. If the bicycle
has been turned upside down or on its side, be sure to operate the brake lever a few
times to check that the brakes operate normally before riding the bicycle, and if the
brakes do not operate normally, adjust them according to the following procedure.
If brake does not seem to work (feels sluggish) when the brake lever is depressed
Set the bleed section of the brake lever so that it is parallel to the ground, and then
gently depress the brake lever several times and wait for the air bubbles to return to the
reservoir tank.
If the brakes lever still feels sluggish, bleed the air (refer to "Adding mineral oil and
bleeding air").
• If the quick release lever on the hub is on the same side as the disc brake rotor, they may
interfere with each other, which is dangerous, so check that they do not.
• SHIMANO disc brake systems are not compatible with tandem bicycles. Because tandem
bicycles are heavier, the stress on the brake system increases during brake operation. If
hydraulic disc brakes are used with tandem bicycles, the oil temperature will become too
high and vapor locks or ruptures in the brake hoses may occur, causing the brakes to fail.
• When installing the brake caliper using bolt
Bolt fixing pin
fixing pins, be sure to use mounting bolts of
the appropriate length.
If not, the bolt fixing pins may not be securely
fastened, and the bolts may fall out.
Brake hose
• After installing the brake hose to the brake unit, adding SHIMANO genuine mineral oil
and bleeding air bubbles, depress the brake lever several times to check that the brakes
are operating normally and there are no fluid leaks from the hose or the system.

• Secure the electric wires with a zip tie so that they do not interfere with the gears or
tires.
• The strength of the adhesive is fairly weak to prevent the paint on the frame from being
peeled off 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. Otherwise, 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
poor contact.
Rear derailleur
• Be sure to adjust the top adjustment bolt and the low adjustment bolt 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 derailleur 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 derailleur.

TO ENSURE SAFETY
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 is 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 then
try again. (Note that some oil may overflow from the reservoir tank at this time.)
• 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 reassembled 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 a 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, component compatibility or product
functionality may suffer.

TO ENSURE SAFETY
Be sure to also inform users of the following:
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, approximately 1 minute is usually required for the system
power to reset.
In the case of using SM-BTR1
• Remove the battery from the battery mount. After approximately 1 minute, install the
battery.
If using SM-BTR2/BT-DN110/BT-DN110-A
• Disconnect the plug from SM-BTR2/BT-DN110/BT-DN110-A. After approximately 1 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 an 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 compatibility with E-TUBE
• Check the following website for information on compatibility with each unit and
functional limitations.
When routing wires through the inside of the frame, be sure to do so before installing each
component. The wiring diagram for using an external battery is shown below.
NOTICE
• When passing the wires through the inside of the frame, especially when pulling
junction [B] into the frame, it is necessary to finish wiring and check the connection
before installing the bottom bracket. This is particularly important when you use a
press-fit bottom bracket.
Wiring example for installing junction [B] on the outside
In this wiring example, junction [B] is located on the lower side of the frame. In many cases,
most of the wiring will be external.
` When using junction [A] on the outside
Use an external type junction [A]. In this wiring example, all electric wires are external.
