The chain of the mountain bike is maintained according to the use of the condition, such as full lubrication before off-roading, timely cleaning of sediment after off-road, oiling lubrication and rust-proof, and the chain with sediment has great damage to the chain and flywheel. (Generally, it is best to maintain it once before and after each off-road).

According to the use of the variable speed line pipe, about half a year to a year or so to add graphite lubricant

The brake is a guarantee of safety, and it is best to check whether the cable (V or line disc) or oil pipe (oil disc) is defective before each off-road, whether the stroke needs to be adjusted, and whether the rebound is in place

The fork usually pays attention to dustproof, and it is best to disassemble and maintain it once a year or so, and the off-road time is slightly shortened

Generally, cranksets and flywheels do not require special lubrication, lubrication chains are sufficient

Hubs, generally no problem just leave it alone

It is best to check the rim from time to time for deflection, broken wires, etc

Last but not least, the tightening of the screws is very important, it is very dangerous to loosen during riding

You can go directly to the store for care, and it is generally oiled and adjusted to the brakes or something, pay attention not to break the car paint in general, in case of rust

About how to maintain it.

It is not specific to the specific model of the car.

As one of the harder mountain bikes, don't let your bike ride on too bumpy roads.

You won't be comfortable, and neither will your car.

The fork of the 770 is not very good and easy to break, so please unlock it if it is not on a smooth road.

It is very important to adjust the shunting in the early stage, and it is recommended to adjust it yourself, including braking and speed change and sitting height.

If you brake, adjust it according to your use, don't adjust it too tightly when you are on weekdays, because the braking distance becomes very long if the wheels are locked, and if you play stunts, the rear brake is tightened to a light pinch to lock, and the front brake is adjusted to pinch to the end

V brake is not good to grasp this extent, it is recommended to change the oil disc front disc. If you have money, you can front and rear oil dishes.

Variable speed, there are detailed tutorials on the Internet、、、 don't let your car's chain and flywheel crankset dial forward and backward dial is the truth of maintenance!

The sitting height is adjusted according to your preferences, generally adjusted to the bottom of the pedal leg can be straightened 90%, too short to ride tired, too high will not reach the pedal, specific weighing, anyway, 770 is a quick release of the seatpost.

For later maintenance, buy a chain washer and put some oil on the sludge for the car's walking mechanism

Look at what you said only once a week or two, when you don't usually ride, you have to put the gear line to the loosest state, that is, the front 1 and the back 8

When riding a bicycle or changing speeds, do not push too hard to change speeds.

Don't crash! By all means! This requires you to jump at a good angle, and if you are in the field, you can directly put the car flat on the ground.

If you can't fall at the front dial, you can choose to install a guard pipe, which is a U-shaped aluminum alloy pipe that can protect the rear dial, and you won't fall down if you crash.

You can also talk to me about the car.

What is the maintenance of a bicycle, but if you don't ride it for a long time, there are a few precautions, the first tire pressure should not be too large, the speed is loose to the end Keep it elastic Try not to fall dust, because your chain and flywheel are oily, nothing else A broken car There is nothing cute to cherish.

The car should be oiled for 3 months, usually do not expose to the sun, do not get wet in the rain (to prevent rust), usually when you wipe the car yourself, check whether the screws are loose, and other small faults.

The bicycle itself is a simple means of transportation, not as many detailed rules as car maintenance.

Frequently wipe the various parts of the car with a soft towel, remove it and clean it up if you disassemble it quickly, empty the sand and gravel in the gap, remove the entire wheel from the rear wheel group, clean the wheel block with a towel, pour kerosene or gasoline into the chain to clean up the gravel of the chain, and keep the return pipe of the fork as clean as possible, it is best to buy a chain guard and stick it to the right rear triangle to prevent the chain from hitting the frame and causing wear, and finally remember to put chain oil on the chain.

If you need to maintain it, you can do it yourself, such as adjusting the brakes and transmission, whether the brakes are sensitive, whether the front and rear dials are rubbed when changing gears, and if there is a big problem, such as the fork leaking oil and air leakage or something, this can only go to the store to find someone to sort out.

Precautions when loading: do not drop the parts, adjust the most suitable posture, etc.

1. Keep it clean.

Clean up the bike. Start by finding a place to flip it upside down, balance the seat and handlebars, and prepare the tools we need: a bike cleaning brush, a degreasing solvent, chain lubricant, a towel, a bucket, tap water and a hose.

Pay close attention to your car's drivetrain (bearings) and chain when washing your car, and spray some degreasing solvent on it if it has oil, rust or dirt. Wash the body of your mountain bike, but also make sure that the bottom bracket and wheels do not touch the water, otherwise it will cause rust. After each wash of the bike, dry it with a towel.

2. Apply lubricating oil.

Don't forget to lubricate your mountain bike regularly. So how to get the right number lubricating oil? Under-lubrication and over-lubrication can cause your mountain bike to be tougher to ride.

So how do you make a perfect lubrication? First of all, use a bike-specific lubricant (just buy it) that is neither too thin (it will dissolve too quickly) nor too thick (it will attract dust and dirt), squeeze from the top and bottom to each link, and slowly turn the pedal with one hand while squeezing the lube. Generally speaking, a thin layer of lubricant is sufficient, unless you live in a place where there is a lot of rain, then applying a slightly thicker layer can reduce the number of maintenance.

Then use a rag to remove the excess lubricating oil.

In addition, lubricating oil can be used for every part of the bicycle that can be rotated (bearings).

3. Check the bike.

Check your bike up and down for anything wrong and tighten loose bolts, including the crank arms and chainrings. Replace worn parts. (mountain bike pedals, tires, handlebars, etc.). Empty pedaling the bike and check the front and rear brakes.

Basically, there is nothing to maintain, 770 is an all-alloy car, it will not rust, try to wipe the car when you come back from a long distance, do not wash, try not to contact the water with the hub, there is often dust on the fork, you must wipe it off often, and the rest is gone, at most the chain is oiled. A bicycle is a simple piece of machinery that is nothing to maintain.

If you maintain it, as long as you pay more attention to the chain and flywheel part, it will be good to wipe the chain with sewing machine oil every other month Remember to wipe off the original floating soil and dust before wiping Because the sewing machine oil is relatively clean **It is also cheaper Or you can also go to the store to sell bottle house stone Bicycle maintenance oil There are some other maintenance that you can not complete at home Like the maintenance of the front and rear axles, go to the store every year or so to maintain the front fork theoretically also needs maintenance But the maintenance oil of the fork** Relatively high, the store is to charge to get it, followed by the speed of the word, there is nothing, there is the problem of the rim, pay attention to the brake block do not wear too badly, hurt the rim can.

Bicycle maintenance.

1.Essential Tools:

1 Movable wrench or open-end wrench.

2 Allen wrench.

3 Screwdriver: There are two types: slotted and Phillips.

4 Tire removal lever: used when removing the outer tire.

5. Tire repair rubber and tire patch: for tire repair.

6 Chain beater: disassemble the chain for use.

7 Wire wrench: used to adjust the wire tension of the rim.

8. Lubricating oil: There are three kinds of lubricating oil: butter, chain oil and general lubricating oil.

2.Check the wheels: The wheels carry the weight of the whole vehicle and the impact of the uneven road surface, and must be repaired frequently.

Lift the wheel and rotate, the rotation should be stable, if there is shaking, the bolt should be turned or sent for repair. Check whether the tire pressure is sufficient, check the tire wall for cracks, cuts, whether the tread is too shallow, and replace the outer tire if necessary.

3.Check the brakes: pull the left and right brake handles respectively, and push the car forward to check the braking function; The brake pads should be parallel to the rim and maintain a centimeter clearance; Update the split brake line to remove debris from the brake pad to ensure its braking strength, and if it is severely worn, it must be renewed.

4.Check the tooth plate: whether the tooth plate is aligned, whether the tooth tip is bent or missing, and the tooth plate is normal to drive the chain smoothly. Adjust the front shift handle, adjust the chain bar to the maximum tooth plate, if the tip of the tooth will expose the chain, it means that the chain bar is worn and should be updated.

5.Check the flywheel: whether the tip of the flywheel is bent or missing; After adjusting the gear knob, adjust one level at a time, turn the crank, let each speed flywheel rotate for a period of time, check whether there will be tooth jumping, and lubricating oil can be applied to increase the flexibility of operation.

6.Check the chain: the chain will be elongated after long-term use, the pitch of the chain is inches, measure the 24-section chain, the length should be 12 inches, if its length has exceeded the normal length of 1 8 inches, the chain should be replaced.

7.Check the handlebars: Clamp the front wheels with your legs and twist the handlebars, which are straight and locked. Use a hexagonal wrench to put in the bolt slot, and turn clockwise to lock, and counterclockwise to loosen.

8.Check the crank: when stepping on, the loose crank will have a clicky noise: when checking the crank, first swing the crank horizontally, press down with both hands at the same time, and then turn the crank 180 degrees, swing the horizontal position, and press down with both hands at the same time; If the crank is loose, the bolt should be locked.

9.Check the tires: Check the treads, and renew the tires with wear and cracks. When pumping, inflate to the standard tire pressure (about 40-60 psi, subject to tire labeling).

10.Check the pedal: turn the pedal, it should run smoothly and will not slip sideways, if there is clamping, noise, bending, loosening, damage, it should be repaired or updated.
