Variable speed bicycle grinding chain, how to install the chain of variable speed bicycle car

As above, the transmission is not properly adjusted or the cable is loose.

If there is no problem with the maximum and minimum gears of the shift, there is no need to adjust the H and L screws of the derailleur. It's relatively easy to adjust.

You can try to adjust the finger dial, and there is a knob at the front cable to fine-tune. When riding, it can be changed to debugging while riding. However, it is better for newbies to adjust at the car dealership.

There is also the use of a transmission, which should be the most suitable when it feels strong on the feet but there is not much resistance. In this way, it is not easy to get tired and strain after long rides. Of course, a few kilometers of urban roads can be changed in any way you like.

Don't fly the most to the maximum, and the smallest disc to the smallest to fly well.

Typical transmissions are not properly tuned or the wires are loose.

It is difficult for novices to adjust by themselves, and it takes experience to adjust it well, and it is the obligation to sell the car to the store where the car was purchased.

In addition, tell you how to change the speed: the smallest 3-4 behind the front large strip, 3-5 in the middle behind the middle strip, and 3-4 in the back of the small strip with large teeth, for a reason.

1.That's all there is to the low-end car.

2.Although high-end cars have high precision, so has the scientific change.

Change it yourself to see if your 123 corresponds to the size or size of the front and rear teeth, and master the method to ride well.

The transmission is not adjusted well, this self-tuning is generally not good for novices, find a car dealership, just a few minutes, and generally will not charge you money.

Remove the cable of the rear transmission and tighten it and put it on.

If the front wheel is large and the rear one, try not to grind.

Speed bicycle chain installation method:

1. Thread the chain through the front derailleur and hang it on the smallest crankset.

2. Hang the chain on the smallest wheel.

3. Hang the chain on the front guide wheel that is pulled back.

4. Hang the chain on the rear guide wheel that is pulled back. Socks closed such as.

5. Tighten the chain, but don't live too much after pulling it back (the smaller the better), and don't fall.

6. On the premise of not falling, count four nodes backward from the node that is aligned with or close to the chain street, and the four nodes of the first state are the places that need to be truncated.

7. Clamp the chain on the connector and cut off the chain with the connector.

8. Connect the two ends of the chain together.

9. Press the chain node into the chain with a chain cutter.

10. Press the node into the chain, and the outside of the node is parallel to the outside of the chain, and there should be no protruding parts.

Here's how to fix a loose bicycle chain:

Prepare the material: a wrench.

1. First relax the screw of the scrambling wheel on the right side of the rear wheel of the bicycle that fixes the slow letter auxiliary wheel.

2. Take off the training wheel.

3. You can see that there is a big screw at the innermost part of the screw, <>4. This is to fix the rear wheel, and relax this screw.

5. Then use your hands to pull the rear wheel back and <>

6. You can also knock the fixed rear wheel bearing back a little to try the tightness of the chain.

7. Tighten the screws that fix the rear wheel and <>

8. Then install the training wheels.

9. Well, look at the chain is indeed much tighter than before, and it is not easy to fall off when riding.

You can go to the after-sales service of Youzhen Silver to see the wear and tear of the chain travel clearance, if it has passed the limit value, change the chain; The teeth of the wheel may also be worn, just change the flywheel chain; Also see if the teeth of the crankset are also sharpened; It may also be that the chain flywheel is overworn, and the chain can't grasp the tip of the tooth, so it is recommended to replace the chain flywheel crankset with a new one, and it must be replaced together.

Expand the banquet and exhibition information:Chains are most vulnerable to injury:

1. It is the most prone to rust.

2. It is the easiest to generate oil sludge.

3. It is the most susceptible to wear.

Timing of chain maintenance:

1. There is too much dust and sludge on the chain.

2. The transmission system produces abnormal noise when riding.

3. The performance of the transmission decreases when changing the speed (the transmission is not in place, etc.).

4. After not riding for a long time after rain, after placing it at home.

5. Long-term or long-distance riding.

Some chains have a velcro fastener that can be released with a single clip of needle-nose pliers, and then snapped up again through the crankset and flywheel. If you don't have a magic buckle, you need to use a chain cutter, first open the column of the chain connection part with a chain cutter, and then connect it after installation.

You can buy a cheap bicycle chain adapter (around 15 yuan), or add a magic chain buckle to the chain (quick-release chain buckle 15 to 35 yuan).

Cleaning - Clean your chain after every ride, especially in rain and humidity.

Take care to use a dry cloth to wipe the chain and its accessories.

If necessary, use an old toothbrush to clean the gaps between the chains.

Don't forget to clean the front and rear transmission wheels.

Use a brush to remove the dirt and dirt that has accumulated between the chains, and if necessary, use warm soapy water.

Do not use strong acids or alkaline cleaners (such as rust removers) as these chemicals can cause damage or even breakage of the chain.

Do not use a chain washer with added solvents to wash the chain, as this will definitely damage the chain.

Avoid the use of organic solvents such as stain remover oil, which not only damages the environment but also washes away the lubricating oil in the bearing area.

Lubrication - Always apply lubrication after each cleaning, wiping, or solvent cleaning of the chain. (It is not recommended to use organic solvents to clean the chain).

Make sure your chain is dry before applying the lube.

The lubricating oil is penetrated into the chain bearing and allowed to thicken or dry. This ensures that the parts of the chain that are prone to wear and tear can be reliably lubricated.

To confirm that you are using the right lubricant, you can pour some on your hands to test. Good lube, at first it feels like water (penetration), but too.

Over time, it will become viscous or dry (long-lasting lubrication).

To avoid clogging with excess lubricating oil, simply apply oil to key parts of the chain, such as rollers. After oiling, it will be possible to reduce the number of times the chain is running.

Abrasion and abrasion.

In other parts of the chain, only a little lubrication is needed to prevent rust.

Wipe off excess lubricating oil from the surface of the chain.

In the case of transmissions, it is also necessary to pay attention to rear transmission pulleys, gears and flywheels. Apply the same principles to the maintenance and lubrication of these parts.

After lubricating the oil, use a dry cloth to wipe off the excess oil on the chain to avoid dirt and dust adhesion.

Before reattaching the chain, remember to clean the chain connections to make sure no dirt remains.

After the chain is cleaned, lubricating oil should also be applied to the inside and outside of the coupling before assembling the joint.

Your dad is using the old way to maintain your car, hehe

The chain is washed with dish soap, or laundry detergent, and then wiped dry by all means! If possible, use a chain washer and kerosene, and clean it very cleanly.

Hope it helps

Remove and soak in kerosene for half an hour.

Rinse out, dry and oil the chain.

I went to the bicycle shop to buy lubricant, I bought it for 50 yuan, ** it is okay, it may be fake.

You don't need to clean it up, just get some oil and put it on.

Bicycle chains can be damaged to varying degrees depending on the person's habits, such as environmental factors, the rider's riding condition, and the level of maintenance of each individual, but the most important ones are two main points: preventing unnecessary chain wear and checking the chain extension.

1. Prevent unnecessary chain wear.

1.When shifting gears, try to keep the chain vertically between the large chainring and the flywheel. (Especially in extreme gears such as the smallest gear with the smallest flywheel, or the largest gear with the largest flywheel.) ）

2.When shifting gears, take into account road conditions (e.g. uphill, upshift early to avoid excessive force attached to the chain when changing gears.) ）

3.Before stopping, change to the smallest gear to avoid the need to change gears when stationary.

Others use 2 or 3 chains at the same time and replace them weekly (or every 500-700 km), which is said to reduce wear, especially for more expensive gears and flywheels.

2. Check the elongation of the chain.

The easiest way to check the chain extension is when you feel the smoothness of the chain when it loses transmission and the agility when changing gears.

Rough detection methods are:

1.Turn the chain to the outermost ring and pull it up from the middle of the gear.

1. The dust disturbance bicycle chain has an interface that can be removed.

2. The gap between the aging chain and the chain is too large, and the chain and sprocket are replaced.

3. If a joint in the middle of the chain is damaged, it can be replaced individually.

4. The chain often falls off, the front and rear wheels are not in a straight line or the chain is too loose, adjust the position of the rear wheels.

Code words are hard, hope.

Broken? Dropped? Or what's wrong?
