Chain length on bicycles with rear suspension
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.

Install the inner hole cover by turning it as
shown in the illustration until it stops.
Do not turn it any further than this,
otherwise it may damage the screw
thread.
Operate the lever (B) 9 times or more
to set the lever to the highest position.
Then remove the inner hole cover and
connect the inner cable.

Cutting the outer casing
When cutting the outer casing, cut the
opposite end to the end with the marking.
After cutting the outer casing, make the
end round so that the inside of the hole has a uniform diameter.
Attach the same outer
end cap to the cut end
of the outer casing.

“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, this chain has a forward side and a reverse side, and the
sides are marked so that the chain will face the correct way when installed. The proper design performance
will be obtained when the chain is installed so that it faces the correct way. If it is installed so that it faces
the opposite way, the chain may come off and the bicycle may fall over and serious injury may occur as a
result.
•Checkthatthewheelsarefastenedsecurelybeforeridingthebicycle.Ifthewheelsarelooseinanyway,theymaycomeoffthe

•Usethereinforcedconnectingpinonlyforconnecting
the narrow type of chain.
•Ifconnectingpinsotherthanreinforcedconnectingpins
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.
•Ifitisnecessarytoadjustthelengthofthechaindueto
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.
•Checkthatthetensionofthechainiscorrectandthatthechainisnotdamaged.Ifthetension
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. 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.
•Obtain and read the service instructions carefully prior to installing the 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.

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.
Tightening torque:
30 - 50 N·m {261 - 434 in. lbs.}
For each sprocket, the surface that has the group mark should face
outward and be positioned so that the wider part of each sprocket
and the A part (where the groove width is wide) of the freewheel
body are aligned.

Gear shifting operation
The INSTANT RELEASE mechanism makes fast releasing possible because cable tension is released immediately when a lever is
depressed. The levers are also equipped with 2-WAY RELEASE and MULTI RELEASE mechanisms so that you can now shift two gears
with a single operation, either by pushing or pulling the lever.
Both lever (A) and lever (B) always return to the initial position when they are released after shifting. When operating one of the levers,
always be sure to turn the crank arm at the same time.

their recommendation on tightening torque in order to prevent over
tightening that can cause damage to the carbon material and/or
under tightening that can cause lack of fixing strength for the
components.
