General rules for service the bike
Any bicycle requires service, cleaning and lubrication - not only before the opening of the season, when most cyclists in the spring take out their bikes and begin to prepare them for summer, but also throughout the entire riding period. In addition, some owners engage in cycling all year round or with a short break.
The more intensively and more often a bicycle is used, the more attention needs to be paid to its working condition.
The basic rules of the service are simple
1. The undercarriage must be clean.
2. The chain, cassette, stars and switches are lubricated and do not creak.
3. Tires - inflated.
About the need for service

Bike cleaning
What is the best way to wash a bike?
We begin the washing of the bicycle with a bucket of warm water and a portion of a special cycle shampoo. They are intended for use on painted metal and / or carbon fiber. Many cleaning products are sold in concentrated form and must be diluted with water.
If the bike has a lot of dirt, cleansing sprays are used to help get rid of dirt faster. After the spray is applied, you need to wait a few minutes for it to work, then rinse with water or a damp cloth, and in hard-to-reach places with a brush.
Degreasers will be needed to remove heavy contaminants. These tools will certainly come in handy for cleaning the chain and other moving parts of the transmission, the purity of which depends on its trouble-free operation. It is no secret that dirt on these elements leads to premature wear of parts.
How to wash a bike?
It is best to spray water on the frame and rim before applying special detergents and let the bike stand for a while.
Severe contamination is best rinsed with a jet of water first, rather than starting to immediately rub the bicycle frame with a sponge, as hard particles of dust, soil or sand can scratch the paint, which causes premature corrosion of the metal.
Do not wash your bike like a car, directing a powerful stream of water at it. A high pressure easily flushes the grease out of the chain, and on most mountain bike models, bearings accumulate water, which is rather problematic to drain.
