NOTE:
If gear shifting operations do not feel smooth, wash the derailleur and lubricate all moving parts. •
If the amount of looseness in the links is so great that adjustment is not possible, you should •
replace the derailleur.
You should periodically clean the derailleur and lubricate all moving parts (mechanism and •
pulleys).
If gear shifting adjustment cannot be carried out, check the degree of parallelism at the rear end of •
the bicycle. Also check if the cable is lubricated and if the outer casing is too long or too short.
If you hear abnormal noise as a result of looseness in a pulley, you should replace the pulley. •
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. •
Use a frame with internal cable routing is strongly discouraged as it has tendencies to impair the •
SIS shifting function due to its high cable resistance.
Always be sure to use the sprocket set bearing the same group marks. •
Never use in combination with a sprocket bearing a different group
mark.
Use an outer casing which still has some length to spare even when •
the handlebars are turned all the way to both sides. Furthermore,
check that the shifting lever does not touch the bicycle frame when the
handlebars are turned all the way.
A special grease is used for the gear shifting cable (SIS-SP41). Do not •
use DURA-ACE grease or other types of grease, otherwise they may
cause deterioration in gear shifting performance.
Grease the inner cable and the inside of the outer casing before use to •
ensure that they slide properly.
For smooth operation, use the specified outer casing and the bottom bracket cable guide. •
Operation of the levers related to gear shifting should be made only when the front chainwheel is •
turning.
If the brake fluid used in the oil disc brakes is of a type which tends to adhere to the plastic parts •
of the shifting lever, this may cause the plastic parts to crack or become discolored. Therefore,
you should make sure that the brake fluid does not adhere to these plastic parts. The mineral oil
which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to
plastic parts, but such parts should be cleaned with alcohol beforehand to prevent foreign particles
from adhering.
Do not disassemble the indicator and shifting lever unit, as this may damage them or cause mis- •
operation.
Parts are not guaranteed against natural wear or deterioration resulting from normal use. •
For maximum performance we highly recommend Shimano lubricants and maintenance products •
For any questions regarding methods of installation, adjustment, maintenance or operation, •
please contact a professional bicycle dealer.
This release lever is equipped with a 2-way release mechanism which allows release operations to
be carried out by either 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.
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.
