• Make sure that the connecting pin is aligned with
the outer link surface from the side that the pin is
inserted. It should feel smooth and flush when you
run your finger over it. The pin will protrude slightly
on the backside after the break off pin is removed.

• If it is necessary to adjust the length of the chain
due to a change in the number of sprocket teeth,
make the cut at some other place than the place
where the chain has been joined using a
reinforced connecting pin. The chain will be
damaged if it is cut at a place where it has been
joined with a reinforced connecting pin.

• When readjusting the length of the chain, be
sure to insert the reinforced connecting pin from
the same side as the chain cutter was inserted (the same direction as when
the chain was cut).

• Check that the tension of the chain is correct and that the chain is not
damaged. If the tension is too weak or the chain is damaged, the chain
should be replaced. If this is not done, the chain may break and cause
serious injury.

• Obtain and read the service instructions carefully prior to installing the
parts. We strongly recommend only using genuine Shimano replacement
parts. If adjustments are not carried out correctly, the chain may come off
and this may cause you to fall off the bicycle which could result in serious
injury.

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

Features

In order to provide greater connecting
strength, this reinforced connecting pin has a
special shape (the pin is thicker at both ends
than at the barrel). A guide for making the pin
easier to push into the chain is also provided.

As illustrated in Fig.A, we strongly recommend
to set the connecting pin in the hole of the
outer link on the front side in the direction of
travel. The chain’s level of strength is
enhanced compared to the method in Fig.B.

“Maintenance interval depends on the usage and riding
circumstances. Clean regularly the chain with an
appropriate chaincleaner. Never use alkali based or acid
based solvents such as rust cleaners. If those solvent be
used chain might break and cause serious injury.”

• Use the reinforced connecting pin only for connecting the narrow type of
chain.

• If connecting pins other than reinforced connecting pins are used, or if a
reinforced connecting pin or tool which is not suitable for the type of chain is
used, sufficient connection force may not be obtained, which could cause the
chain to break or fall off.
