About the multi-shift function
On this system, the multi-shift function can be configured using E-TUBE PROJECT. The gears will continue to shift when the shifting switch is pressed
using the multi-shift function. Shifting speed setting for multi-shift can also be modified. When modifying the gear changing settings for multi-shift,
carefully read "Settings customizable in E-TUBE PROJECT" in this dealer's manual.
If crank revolutions are set to low under faster setting of the multi-shift shifting speed, the chain will be unable to follow the movement of the rear
derailleur, possibly leading to issues such as the chain slipping over the tip of the cassette sprocket teeth, the cassette sprocket deforming, or the chain
breaking.

TO ENSURE SAFETY

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 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.
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.

Dual control lever
Because of the characteristics of the carbon fiber material, the lever should never be altered. Otherwise, the lever may break preventing braking
operation.
Check before riding that there is no damage such as carbon peeling or cracking. If there is any damage, stop using the bicycle and consult a dealer or
an agency. Otherwise, the lever may break preventing braking operation.
For Installation to the Bicycle, and Maintenance:

When the shifting switch is operated, the motor which drives the front derailleur will operate to the shifting position without stopping, so be careful
not to get your fingers caught.

TO ENSURE SAFETY
NOTE

Be sure to rotate the crank when carrying out any operations which are related to gear shifting.
Do not keep connecting and disconnecting the small waterproof connector. It may impair the function.
Be careful not to get water into the terminal.
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 product carefully, and avoid subjecting it to any strong shocks.
Do not use thinners or similar substances to clean the products. Such substances may damage the surfaces.
If gear shifting operations do not feel smooth, wash the derailleur and lubricate all moving parts.
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 bicycle dealer.
Charging can be carried out at any time regardless of the amount of charge remaining. 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.
If the battery has become completely empty, 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; and it is recommended that you charge the battery about every six months.
If the storage temperature is 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 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.
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.)
10

SM-BCR2: Battery charger/PC linkage device for SM-BTR2/BT-DN110

Connect the PC linkage device directly to a computer, without using an intermediate device such as a USB hub.
Do not ride the bicycle while the PC linkage device and cable are still connected to it.
Do not connect two or more of the same units to the same connection point. If this is not done, the units may not operate correctly.
Do not connect or disconnect units again while unit recognition is in progress or after recognition is complete. 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 device 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 charger is connected.

Rear derailleur
If gear shifting operations do not feel smooth, wash the derailleur and lubricate all moving parts.
If the chain keeps skipping, ask the place of purchase to replace the chainrings, sprockets and/or the chain.
If there is a large gap in the pulleys which causes a lot of noise, ask the place of purchase to replace the pulleys.
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.
If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur.
11
TO ENSURE SAFETY

Dual control lever
In the case of carbon levers, wash them with a soft cloth using a neutral detergent. Otherwise, the material may break down and be damaged.
Avoid leaving the carbon levers in areas of high temperature. Also keep them well away from fire.
For Installation to the Bicycle, and Maintenance:

Be sure to attach dummy plugs to any unused terminals.
Be sure to use Shimano original tool TL-EW02 to remove the electric wires.
The motors of the motor unit cannot be repaired.
Contact Shimano for information regarding the shipment of the battery charger to South Korea and Malaysia.
Use an outer casing which still has some length to spare even when the handlebars are turned all the way to both sides. Furthermore, check that the
shifting lever does not touch the bicycle frame when the handlebars are turned all the way.
Use the specified cable and cable guide for smooth operation.

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 contact.

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.

Rear derailleur
Always be sure to adjust the top adjustment bolt and the low adjustment bolt according to the instructions given in the adjustment section.
If these bolts are not adjusted, the chain may become clamped between the spokes and the smallest 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 parallel of the rear fork ends.
The tension pulley has an arrow on it to indicate the direction of rotation. Install the tension pulley so that the arrow is pointing clockwise when
looking at the outer side of the derailleur.

SM-BMR1/Battery mount
This is supported by the firmware versions 2.0.0 and later.
The actual product may differ from the illustration because this manual is intended mainly to explain the procedures for using
the product.

Installation of the dual control lever and brake cable
BC-9000 Inner cable Outer casing
1.6mm 5mm
WARNING
Do not apply grease or other lubricants to the inner cable.
Be sure to wipe off with a cloth any grease that adheres to the inner fixing section. After wiping off the grease, pass the inner cable through the outer casing. If
grease adheres to the fixing section, the holding force of the brake cable may not be sufficient. If the holding force is insufficient, the brake cable will slacken
resulting in a loss of brake control and possibly severe injury.
NOTE
Be careful not let the BC-9000 inner cable come into contact with the brake lever or the metal section (adjustment section) of the caliper brake. Fuzz may be
generated when the inner cable is installed or when the coating is damaged during use, but this will not affect its functions.
Use cables which are long enough that they still have some looseness even when the handlebars are turned all the way to both sides.
TECH TIPS
For information on how to install the brake cable, refer to BR-9000 dealer's manual.
