Chain
The chain is a wearing part that has to be lu-
bricated regularly and to be changed at signs
of excessive wear and tear.
Lubricating the chain
Diligent lubrication is important.The chain of
your Street Machine GT is approximately 2.5
times longer than a standard bicycle chain (ap-
prox. 3.8 m). But it also lasts longer since a
chain only wears while bending at the sprok-
kets and the chain rings.
Use a good chain oil that won't leave a sticky
film on the chain.The chain oil may not con-
tain any aggressive chemical substances that
might affect the surface of the chain tube.
Specialist stores sell biodegradable lubricants.
HP V
ELOTECHNIK solely recommends
PROFI
DRYLUBE.This lubricant is purely based on
PTFE (Teflon) that keeps the chain clean and
dry.This way dirt simply falls off and the tubes
(also made of Teflon) always stay clean.Your
dealer can obtain it from HP V

.
It is important that you clean the chain with an
oily cloth before lubricating. Otherwise the
fresh oil washes the dirt that clings to the
chain into the gaps and the bushings where the
dirt causes heavy wear.
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 torch or
boil it in chain grease.
An effective protection against corrosion is
critical 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, protects from corro-
sion 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.

Danger! Take care not to pour any oil on
the rims, brake discs or the tires.The brake
system could fail or the tires could slip away
suddenly.The oil affects the rubber of your
tires and could damage them.While lubrica-
ting cover the surrounding area with an old
newspaper.
