In order to realize the best performance, we recommend that the following combination be
used.
Series
• To replace the sprockets, use the
special tool (TL-HG16) and TL-SR20
to remove the lock ring.
After removing the hub
axle, remove the freewheel
body fixing bolt (inside
the freewheel body),
and then replace the
freewheel body.
The length of A will vary depending on the movement of the
rear suspension. Because of this, an excessive load may
be placed on the drive system if the chain length is too
short. Set the length of the chain by adding two links to the
chain when the rear suspension is at a position where
dimension "A" is longest and the chain is on the largest
sprocket and the largest chainring. If the amount of
movement of the rear suspension is large, the slack in the
chain
may not be taken up properly when the chain is on the
smallest chainring and smallest sprocket.

Best setting
The best setting is when the shifting lever is
operated just enough to take up the play and the
chain touches the 3rd sprocket and makes noise.
This service instruction explains how to use and maintain the
Shimano bicycle parts which have been used on your new bicycle.
For any questions regarding your bicycle or other matters which
are not related to Shimano parts, please contact the place of
purchase or the bicycle manufacturer.
®
* Return the lever to its original position (the position where
the lever is at the 2nd sprocket setting and it has been released) and
then turn the crank arm clockwise. If the chain is touching the 3rd
sprocket and making noise, turn the outer casing adjustment barrel
clockwise slightly to tighten it until the noise stops and the chain runs
smoothly.
For the best SIS performance, periodically lubricate all
power-transmission parts.
