Chain
The chain is a wearing part that has to be lubricated 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 contain any aggressive chemical substances that might affect the surface of the chain tube.
Specialist stores sell biodegradable lubricants. HP VELOTECHNIK solely recommends PROFIDRYLUBE.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 VELOTECHNIK.
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.
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 lubricating cover the surrounding area with an old newspaper.
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 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.
