General Safety Information
– To avoid serious injuries:
NOTE:
You can shift gears while pedaling, but on rare occasions
the pawls and ratchet inside the hub may produce some
noise afterwards as part of normal gear shifting operation.
The CJ-NX10 cassette joint should only be used with
sprockets from 16T to 23T.
If the wheel becomes stiff and difficult to turn, you should
lubricate it with grease.
Do not apply any lubricant to the inside of the hub,
otherwise the grease will come out.
You should periodically wash the sprockets in a neutral
detergent and then lubricate them again. In addition,
cleaning the chain with neutral detergent and lubricating it
can be a effective way of extending the useful life of the
sprockets and the chain.
If the chain keeps coming off the sprockets during use,
replace the sprockets and the chain.
Parts are not guaranteed against natural wear or
deterioration resulting from normal use.
For maximum performance we highly recommend
Shimano lubricants and maintenance products.
For any questions regarding methods of handling or
adjustment, please contact the place of purchase.
When securing the brake arm to the frame, be sure to
use a brake arm clip that matches the size of the
chainstay, and securely tighten them with the clip screw
and clip nut to the specified tightening torque.
Use a lock nut with a nylon insert (self-locking nut) for the
clip nut. It is recommended that standard Shimano parts
be used for the clip screw, clip nut and brake arm clip.
In addition, use a brake arm clip that matches the size of
the chainstay.
If the clip nut comes off the brake arm, or if the clip screw
or brake arm clip becomes damaged, the brake arm may
rotate on the chainstay and cause the handlebars to jerk
suddenly, or the bicycle wheel may lock and the bicycle
may fall over, causing serious injury.
When installing the hub to the frame, be sure to install
the correct non-turn washers to the left and right sides,
and securely tighten the hub nuts to the specified
torques. If the non-turn washers are installed to one side
only, or if the hub nuts are not tightened sufficiently, the
non-turn washer may fall out, which could cause the hub
axle to rotate and the cassette joint to turn. This may
then cause the handlebars to be accidentally pulled by
the shifting cable, and an extremely serious accident
could result.
Obtain and read the service instructions carefully prior to
installing the parts. Loose, worn, or damaged parts may
cause serious injury to the rider.
We strongly recommend only using genuine Shimano
replacement parts.
Check that the wheels are fastened securely before
riding the bicycle. If the wheels are loose in any way,
they may come off the bicycle and serious injury may
result.
Read these Technical Service Instructions carefully, and
keep them in a safe place for later reference.
Technical Service Instructions
Inter-7 Hub
Cassette joint
Be sure to read these service instructions in conjunction
with the service instructions for the Inter-M Brake and the

WARNING
Place right hand dust cap C onto the driver on the right side
of the hub body. Next, install the sprocket and secure it in
place with the snap ring.

Installation of the sprocket to the
hub
When installing the brake arm clip, securely
tighten the clip screw while holding the clip nut
with a 10 mm spanner.
Note:
After installing the brake arm clip, check that the
clip screw protrudes about 2 – 3 mm from the
surface of the clip nut.
Take up the slack in the chain and secure the wheel to
the frame with the cap nuts.
Fix the brake arm of the Inter-M brake securely to the
chainstay with the brake arm clip.

you don't apply
excessive force
when installing.
Install the brake arm of the Inter-M brake to the
chainstay with the brake arm clip, provisionally tighten
the clip screw and clip nut, and then tighten the brake
unit fixing nut.

Note:
If the brake arm is in the incorrect position as shown
in the illustration so that it cannot be provisionally
installed to the chainstay, loosen the brake unit
fixing nut and turn the brake arm. Then, after
provisionally securing the brake arm to the
chainstay, tighten the brake unit fixing nut.

Place the non-turn washers onto the right side and left
side of the hub axle. At this time, turn the cassette joint
so that the projecting parts of the non-turn washers fit
into the grooves of the fork ends. If this is done, the
cassette joint can be installed so that it is almost parallel
to the chainstay.
