<CN-6701: 10-speed Chain for Road Riding>
• 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.
• In order to obtain good gear shifting performance, applicable chains have a forward side and a reverse side, and
the sides are marked so that the chains will face the correct way when installed. The proper design performance
will be obtained when the chains are installed so that they face the correct way. If the chains are installed so
that they face the opposite way, they may come off and the bicycle may fall over and serious injury may occur
as a result.
Forward (outer side) Reverse (inner side)
The side with the marks shown in the illustration is the forward side (outer side).
• Narrow-type chains must always be connected using reinforced connecting pins.
• If the chain is connected by using connecting pins other than reinforced connecting pins, or by using reinforced connecting
pins or tools which are not suitable for the chain, the connecting force provided maybe insufficient, and the chain may break
or fly off.

• After connecting the chain, be sure to feel the connection with your fingers to check that
both ends of the connecting pin and the surfaces of the links are flush with each other. (The
opposite end of the pin which has been broken off should feel as though it is projecting very
slightly.)
• If the length of the chain needs to be readjusted for reasons such as changes to the sprocket configuration, cut the chain at
a place which is not connected by means of a reinforced connecting pin. If you cut the chain at a place which has been
connected using a reinforced connecting pin, it will damage the chain.

• Use a TL-CN41 chain wear indicator (Y12152000) or a similar tool to check if the chain has become stretched or damaged. If
the chain has become stretched or damaged, it may break and the bicycle may fall over, so the chain should be replaced.
• 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).
• Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise you may fall off the bicycle.
