timing of bicycle chain maintenance:

1. The speed change performance is reduced during riding.

2. Too much dust or sludge on the chain.

3. Noise is generated when the transmission system is running.

4. Due to the dry chain, it makes a rattling sound when pedaling.

5. in the rain after a long time.

When driving on general roads, maintenance is required at least once every two weeks or every 200 kilometers.

7. When driving on off-road conditions, it should be cleaned and maintained at least every 100 kilometers. Even riding in a more vicious environment requires cleaning and maintenance every time.

Cleaning of the chain

Do not soak the chain directly in strong acidic and alkaline detergents such as diesel oil, gasoline, kerosene, WD-40 oil and degreasing agent, because the inner ring bearing of the chain is filled with high viscosity oil (commonly known as butter, English name: grease). Once washed off, the inner ring will be dry and astringent. No matter how much low viscosity chain oil is added afterwards, there is nothing to make up.
