Bicycle Repair Tips

In a rare leisure time, you launched the slightly dusty bicycle out of the garage, took off your suit and shirt, and put on a casual shirt. You were in the soft sunlight, through the narrow alleyway, and the hurriedly rubbing people. Pass by the shoulder, you alone in the city with no purpose in the shuttle, suddenly, you stopped, you look at the beautiful girl in front, you exposed harmless smile "girl, know where the nearest repair shop My car is broken." Here are some tips for repairing cars.

1. Do not clamp the inner tube. Before inflating, make sure that the inner tube is properly installed. Although this step is simple, it is often ignored by riders. First, inflate the valve when it is about half the distance, until the inner tube bulges (about 30%). Next, insert the inner tube into the casing and check that the valve stem is vertical. Then place the casing on the rim edge. Next, turn the tire, press the tire into the rim with your thumb, check the gap, and make sure that the inner tube is not caught between the tire and the rim. Finally, press the valve into the casing and pull it out through the valve hole. Fill the air.

2. Ensure the vehicle is dry. After the rain ride, clean the bike. If it is a steel frame, you have to wipe it clean to prevent rust. If it is not a steel frame, and there is no time to deal with these, then at least dry the drive system, this part is the easiest to "early retirement", followed by the edge of the wheel, if the rustling will only hurt the brake system, wear wheel ring.

3. Oil in time. Mechanical devices also operate violently in the absence of oil - either to take longer to repair or to damage equipment. Either way, it is against you.

4. The drive system removes dirt in time. If the chain is full of grease, spray the chain with a degreaser, then hold the chain with a rag, and turn the pedal in reverse to clean it. Repeat this until the chain can pass through the rag. Finally, clean the gear discs, flywheels, and transmission pulleys to reduce chain wear. Finally lube.

5. Replace the chain. The chain should be changed every 1400-1800 miles, or at least once a year. However, most riders cannot do this. If you use the old chain for a long time, you will wear the flywheel and the sprocket, and you really need to pay for each part instead of just the chain.

6. Scared when shifting speed. This is not only annoying, it's simple, but it also shows that the drivetrain is getting worn out, or the transmission needs to be adjusted. If you encounter this kind of problem, don't use the biggest three gears behind.

7. Let the brakes "scream" silent. If your ring brakes are already complaining, but are not thrown, then clean up the rims and sand the brake pads with abrasive sand to remove surface impurities.

Pay attention to the details to achieve perfection. Everyone should check their equipment in advance during leisure and entertainment, and don't let the accident live up to the good times.
