Bicycle maintenance and repair – chain brush

At present, there are more and more people riding bicycles. Every time they see a rider passing by, they always feel a sense of joy. Cycling can add fun to busy urban life. It can not only exercise, recuperate body and mind, but also Get to know more riders while riding, and bring the happiness of cycling to our life. However, many riders do not have much knowledge of bicycle maintenance, and sometimes it is even a thorny issue.
Let’s learn some knowledge about bicycle maintenance and maintenance, and I will also share with you the little bit of experience I have accumulated.
Let’s start with the chain. I think the chain is the most easily worn and stained part in cycling, and it is also the most tangled and troublesome part for riders, at least for me.
The chain is completely exposed during the riding process, and riding in various environments will be directly affected by the environment. If the chain is not well maintained, it will not only affect the life of the chain, crankset and derailleur, but also affect the riding due to the chain is not smooth enough. feel of the line. Therefore, the maintenance of the chain is extremely critical in daily maintenance.
For chain maintenance, a lot depends on the environment and conditions you are riding. Riding in wet and muddy conditions requires more maintenance than dry and tarmac. Let’s introduce the maintenance time and correct use of bicycle chain.
Timing of chain maintenance:
1. Reduced shifting performance during riding.
2. There is too much dust or sludge on the chain.
3. Noise is generated when the transmission system is running.
4. There is a rattling sound when pedalling because the chain is dry.
5. Place for a long time after raining.
6. When driving on general roads, maintenance is required at least every two weeks or every 200 kilometers.
7. When driving on off-road conditions, it should be cleaned and maintained at least once every 100 kilometers. Even riding in harsher conditions requires cleaning and maintenance every time you ride.

Suggested cleaning method:

My suggestion is not to directly immerse the chain in strong acid and strong alkaline cleaners such as diesel, gasoline, kerosene, WD-40, and degreaser, because the inner ring bearing of the chain is injected with high viscosity oil ( Commonly known as butter, English name: grease), once it is washed off, it will make the inner ring dry, no matter how much low-viscosity chain oil is added afterward, there is nothing to do.

Hot soapy water, hand sanitizer, use a professional chain cleaning brush, and brush directly with water, the cleaning effect is not very good, and it needs to be dried after cleaning, otherwise it will rust.
Special chain cleaners are generally imported products, with good cleaning effect and good lubricating effect. Professional car shops sell them, but the price is relatively expensive, and Taobao also sells them. Those with better economic foundations can consider them.
Metal powder, find a larger container, take a spoonful of it and rinse it with boiling water, remove the chain and put it in the water to clean it with a chain brush.
Advantages: It can easily clean the oil on the chain, and generally does not clean the butter in the inner ring, it is not irritating, and it does not hurt the hands. This thing is often used by masters who do mechanical work to wash their hands. , the security is very strong. Larger hardware stores can buy them (Chint generally sells them), and a kilogram pack is about ten yuan, and the price is affordable.
Disadvantages: Since the auxiliary is water, the chain must be dried or dried after cleaning, which takes a long time.
Using a bicycle chain brush to clean the chain is my usual cleaning method. Personally, I feel that the effect is better. I recommend it to all riders. For riders who need to remove the chain frequently for cleaning, it is recommended to install a magic buckle to save time and effort.
