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 (http://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 them for correct use.
Important Safety Information
Guidelines that require replacement, contact the place of purchase or a
bicycle dealer.
WARNING
BEFORE USE, CAREFULLY READ THE REAR E-THRU 12MM SYSTEM USER'S
MANUAL. IF YOU HAVE ANY QUESTIONS, ASK YOUR DEALER.
The Rear E-Thru 12 mm can be used in combination with a special frame
and a special hub/wheel. If it is used in combination with any other frame
or hub/wheel, it may cause the wheel to become detached from the bicycle
while you are riding and result in serious bodily injury.
If the Rear E-Thru 12 mm is not correctly installed to the bicycle, the wheel
may fall off the bicycle during riding, and serious injury may occur as a
result.
If the E-Thru lever is on the left side (rotor
side) of the frame, make sure that the
E-Thru lever does not interfere with the
rotor (Figure 1). In addition, make sure that
the E-Thru lever does not interfere with
the front fork, frame, parts, accessories,
etc., or come into contact with obstructions
(such as shrubs and rocks) while riding. If
the E-Thru lever loosens owing to
interference or contact with foreign
objects, the wheel will loosen and begin to
rattle. If this occurs, contact the place of
purchase or a bicycle dealer. Riding the
bicycle while the wheel remains loose may
lead to the bicycle collapsing and result in
serious injury.
E-Thru Lever
Rotor
CLOSE position
Figure 1
Do not touch the rotor while handling the E-Thru system. In addition, do
not operate the E-Thru lever while the wheel is turning. The rotor is very
sharp and serious injury may occur as a result of touching it.
The brake calipers and rotor become very hot when the brakes are being
used. To avoid the danger of burns, be sure to check that they have cooled
down suffi ciently after riding the bicycle before handling the E-Thru
system.
Before installing the wheel, remove any foreign particles and dust from
the dropout hole, the axle nuts and the axle openings. Foreign particles or
dust may interfere with the correct installation of the E-Thru system, and if
the hub and axle are not installed correctly, the wheel may come off and
serious injury may occur as a result.
After reading the user's manual carefully, keep it in a safe place for later
reference.
Note
Always check the E-Thru hubs before riding to make sure the wheels are
correctly installed on the bicycle frame. This is especially important after
you park your bicycle in a public place.
Make sure that the E-Thru levers are pushed fully to the CLOSE position
(the side of the lever with the inscription 'CLOSE' must be facing away
from the bicycle). As shown in the illustration, the levers must be tilted,
not rotated.

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.
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.
Are the wheels correctly installed to the frame?
Are the E-Thru levers fully pushed to the CLOSE position?
QUICK CHECK
Lift up the bicycle so that the wheel is off the ground, and give the top of
the tire a few sharp downward blows as shown in Figure 1. Also shake the
wheel from side to side as shown in Figure 2 to make sure that there is
absolutely no looseness in the wheel. This check does not guarantee that the
E-Thru lever has received adequate tightening torque. If you are uncertain as
to whether the E-Thru lever is tightened correctly, repeat the installation
procedure as explained in 'Installing the wheel' in these Service Instructions
before riding the bicycle.

Operation
NOTICE
Always be sure to operate the E-Thru lever with your hand. Never use a
hammer or other object to close the lever. If this is not observed, the
E-Thru system or the frame may be damaged.
What is the E-Thru hub?
It is a mechanism that uses a single E-Thru lever operation on the hub to
enable the wheel to be easily installed and removed.
E-Thru hub function
Tilt the E-Thru lever toward the CLOSE position and clamp the frame to
secure the wheel in the correct position.

Installing the wheel
1. Align the hub shoulder correctly

2. Move the E-Thru lever to the OPEN
position, and insert it into the hole
in the dropout on the side opposite
to where the axle nut is. Pass the
lever axle all the way through until
it reaches the axle nut on the other
side.
3. Turn the E-Thru lever to screw the E-Thru lever axle into the axle nut.
Open and close the E-Thru lever, and tighten the E-Thru lever axle into the
axle nut until the point where some resistance is felt when the E-Thru
lever is at the position parallel to the hub axle while it is being moved
toward the CLOSE position.

4. For safety, make sure that the E-Thru lever runs along the frame when it is
in the CLOSE position. Using just the force of your hand, push the E-Thru
lever with the palm of your hand until it moves all the way to the CLOSE
position. Check that the side of the E-Thru lever with the inscription
'CLOSE' is facing away from the bicycle.
Make sure that the E-Thru lever does not interfere with the front fork,
frame, parts, accessories, etc. In addition, be careful that it does not come
into contact with obstructions (such as shrubs and rocks) while riding. If
the E-Thru lever is not in the correct position, the axle nut needs to be
adjusted. Refer to 'Adjusting the axle nut' for details on how to do this.

If there are any instructions on the tightening position for the E-Thru lever in
the Service Instructions for the frame, follow these instructions when
tightening the E-Thru lever.
Removing the wheel
Move the E-Thru lever from the CLOSE position to the OPEN position, and
then turn the E-Thru lever to remove the E-Thru lever axle from the axle nut.
Once the E-Thru lever axle has been removed from the axle nut, remove the
E-Thru lever axle from the wheel.

Adjusting the axle nut
If instructions on adjusting the axle nut are provided in the Service
Instructions for the frame, observe those instructions.
1. Screw the E-Thru lever axle into the axle nut in step 3 of 'Installing the
wheel', and then turn the axle nut to adjust so that the E-Thru lever moves
to the correct CLOSE position, and then check the torque when the lever is
at the CLOSE position.
2. • If the tightening torque is weak when moving the E-Thru lever to the
CLOSE position, turn the axle nut clockwise. The axle nut can be
adjusted in steps of 1/9th of a turn.
If the E-Thru lever tightening torque which was checked in step 1 is too
strong and the E-Thru lever cannot be easily moved to the CLOSE
position, turn the axle nut counterclockwise to reduce the tightening
torque. Turn the axle nut gradually in steps of 1/9th of a turn without
turning it all at once, to set the tightening torque to the maximum
value which allows the E-Thru lever to be moved.

Fixing torque: Weaker
3. Repeat this adjustment until the correct installation force is obtained at
the correct lever position.
