Installation of the HG sprockets

For each sprocket, the surface that has
the group mark should face outward
and be positioned so that the wide
parts of the gear projections on each
sprocket and the A part (where the
groove width is wide) of the freewheel
body are aligned.

• For installation of the HG sprockets, use the special tool (TL-LR15/LR10) to
tighten the lock ring.

• To replace the HG sprockets, use the special tool (TL-LR15/LR10) and TL-SR21
to remove the lock ring.

The groove is
wide at one
place only.

General Safety Information

WARNING

• 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.

• If using the CS-6600 (13-25T, 14-25T, 15-25T) in combination with a front chainwheel, use a
double chainwheel. If you use it in combination with a triple chainwheel, gear shifting performance
will drop, and the bicycle may fall over and serious injury may result.

• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn or
damaged parts may cause the bicycle to fall over and serious injury may occur as a result. We
strongly recommend only using genuine Shimano replacement parts.

• Read these Technical Service Instructions carefully, and keep them in a safe place for later
reference.

Note

• Do not use the CS-6600/CS-6700 in any combination other than with the 10-speed super narrow
chain. Other chains cannot be used as the sizes do not match.

• An 11T and a 12T lock ring are available for use with the CS-6600/CS-6700. Use whichever lock
ring matches the sprocket configuration.

• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.

• Do not apply any oil 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.

Note:

• When removing and installing the seal, do
it very carefully so that the seal does not
become bent.
When reinstalling the seal, make sure that
it is facing the right way, and insert it as far
as it will go.

• Do not disassemble the dust-proof cover
which is crimped onto the cone.

• Do not attempt to disassemble the
freewheel body, because it may result in a
malfunction.
