Do not use any solvents to clean the chain!
The solvent washes the oil off the bearing
parts, stays there and dilutes the fresh oil so
that a sufficient lubrication is not guaranteed.
If you have treated the chain with a solvent
you will have to heat it up with a hot air gun
or boil it in chain grease.
Danger!
Take care not to pour any
oil on the rims, brake discs or the tires.
The braking system could fail or the tires
could slip away suddenly. The oil affects
the rubber of your tires and can damage it.
While lubricating cover the surrounding
area.
An effective protection against corrosion is
crucial for a long chain life. Some minutes
after you have oiled the chain rub it with a
cloth to remove superfluous oil from the
outer surface. Wax the chain thoroughly with
a wax spray. The wax keeps off water, pro-
tects from corrosion and makes dirt fall off
easily.
If the chain has become wet after riding in the
rain you should put your bicycle in a dry and
heated room, and every day you should turn
the crank and so move the chain until it is dry
again. Otherwise it is difficult for the moisture
in the tubes to evaporate which may lead to
corrosion at the chain.
Replacing the chain
The chain is one of the parts of the bicycle
that will wear out. This shows in a stretching
of the chain. Worn out chains do not fit the
sprockets and chainrings any more and wear
them away very quickly.
Check the chain for lengthening regularly. For
this purpose, try to remove the chain from
the chainring. The chain may come off to a
maximum of 5 mm. For a more precise read-
ing you can buy a chain measurement gauge in
your bicycle shop.
Only use chains that are suitable for the gear
system of your bicycle. Otherwise a precise
gear shifting is not guaranteed any more.
Please consult your dealer on this topic. He
will also assist you in checking your sprockets
and chainrings. A new chain does not fit a
worn sprocket or chainring. We recommend
rust resistant chains from KMC with smoothly
rounded edges. They also provide a good gear
changing performance.
Attention!
When you change the
chain take care that the new chain does
not show any sharp edges or burrs.

delivers spare chains by the
meter via your dealer. For this purpose please
indicate the exact length of your chain or
order it a little bit longer if you want to be
sure it fits. You will need approximately.
3,8 m of chain.
The chain length has to be fitted so that the
arm of the derailleur is not fully stretched
when you shift on the big chainring in front
and the big rear sprocket. The derailleur must
still be able to compensate a shortening of the
chain by 4 cm. Please also see the manual of
the derailleur manufacturer on the choice of
the correct chain length.
Attention!
The chain has to be
closed with a special joining link or a chain
riveting tool that expands the ends of the
rivet while riveting (Rohloff revolver). A
poorly joined chain may break, you can
come off the pedals and fall. If you are in
doubt please have adjustments of the chain
length or the changing of the chain be done
by your bicycle mechanic.
Take care that the joining link is not bigger in
size than the other chain links to avoid irregu-
lar chain sounds. We recommend the joining
links by KMC. Every time you change the
chain you also have to apply a new joining link.
