For many riders, the first tool everyone buys must be an inflatable stick! Especially for road vehicles, due to the high pressure on the road tires, the air is replenished almost every week. If it is a latex inner tube, it is necessary to go out and refuel almost every time. Today, I will teach you how to find the best pump for your car in the crowd.
Buy a pump can't just look at the appearance
The easiest way to do this is to find the best psi-level roll from the side of a common tire and buy an inflator based on this psi, which is an important consideration. Purchased inflators must exceed the recommended tire pressure by at least 50 psi. Otherwise, no matter how heavy you are, you won't have enough tires. Depending on the type of tire, the pressure is between 100 psi and 160 psi or higher. For example, a 700 or 23 ° C tire typically ranges from 100 psi to 120 psi. The tubular tires are 160 psi and above.
tips:
The maximum psi (per square inch) is the maximum amount of air that the inflator can charge into the tire.
Pounds per square inch (psi) and standard US representative strips are unclear for many people, and the following comparative design provides a convenient and fast basis for breathing.
The commonly used tire pressure range is as follows
Highwayvehicle: 80-130psi/5.5-9bar
Comfortable commuter: 35-70psi/2.2-4.8bar
Mountain bike: 30-60psi/2.1-4.2bar

Actual use
Upright pump
As the name implies, the refillable cylinder can stand on the ground, allowing the body to operate the expandable cylinder in a more comfortable and efficient position, and the expandable cylinder has a larger cylinder capacity, which is faster and easier to inflate for the tire. It is the ideal bicycle tire inflation tube. However, due to its large size, it is suitable for transportation at home when used or when going out.
Portable pump
Small and lightweight, it can be placed in the pocket of a car or in a car repair kit. It is one of the essential tools for bicycles. Although the cylinder capacity is not as large as the vertical inflator, the clever mechanism can reduce the capacity of the inflator. Whether it is a mountain tire that requires a large amount of wind or a road tire with a high tire pressure, it can handle it freely.
Tubeless tire special pump
More and more wheels are starting to support tubeless tires, but they require a lot of aeration characteristics in an instant, which is difficult to cope with traditional aerators.
Gas storage pump
The air can be pre-discharged into the cylinder for storage, and the tire can be filled with a large amount of air in an instant to ensure that the sidewall is tightly coupled with the wheel carrier. It is also a powerful weapon to improve the efficiency of logistical support for teams participating in the competition.
Carbon dioxide cylinder pump (C02)
Inevitably, a puncture will occur when you ride out. The carbon dioxide gas cylinder inflator can inflate the tire in an instant, avoiding the inconvenience of using the portable inflator, and is convenient, labor-saving and quick. The cylinder inflation nozzle is very small, easy to carry around and safer to ride out on a bicycle.
Shock absorber pump
Many mountain bikes are equipped with pneumatic shock absorbers that use air pressure as a damping and therefore require inflation. Although the air pressure damper does not require a large amount of inflation, injecting air into the damper requires a lot of pressure and the pressure is finely adjusted very quickly. Only by selecting a special high-pressure inflator can the air be easily and properly infiltrated into the air.
