Pumping a bicycle tire is a very simple task that isn’t as difficult as you might think, as long as you know which tools to use. Identify a correct valve with the pump nozzles and perform the pump properly below you will get the best performance.
1. Van Schrader
Van Schrader, also known as Van USA, is often used for cars. The valve cylinder is usually surrounded by a threaded valve core. To deflate you need to use a tool or object with a small tip like the pen cap to press against the valve tip. Schrader valves are generally wide and have a shorter diameter than Presta or Woods valves. They are often found on cars, of all kinds Mountain bike. To open the Schrader valve, simply remove the rubber cap at the top.
-Step 1: Find out the recommended PSI for your tires. This is usually printed onto the side of your bike tire and will include a range. Never let your tire PSI go below or above the recommended threshold as it will damage the tires and tubes.
-Step 2: Select pump
Find a suitable pump in the warehouse to pump. If you don’t have a pump try borrowing a pump or borrowing it from a friend. If you have a Chrader valve you probably won’t need an adapter. Regularly monitor the pressure of your tire inflating to avoid sputtering and perform a pressure check each time. Usually the gas pumps are very high pressure, you can easily blow the tire without being careful. If you are using a pump with 2 pumps then the larger one is for the Schrader valve. A single intelligent pump can be automatically adjusted to match the Schrader valve. A pump with an opening may require you to reverse an internal rubber stopper to match the Schrader valve. Perform remove the cover and find the rubber button. The larger end needs to be fitted into the Schrader valve.
-Step 3: inflate the tire
Perform inflating to push air into the tire. Remove the rubber cap on the valve and place it somewhere safe like the part of your back pocket. If you don’t want to lose it. Place the pump on the valve if there is a lever near the pump nozzle, make sure it is in the open position (parallel to the pump nozzle) when you put it in the valve, then pull the lever down to the closed position (perpendicular to the nozzle). pump) when it turns on. Hold the valve firmly to prevent high pressure from disabling the pump nozzle. When the pump stops pressure is sufficient, pull the lever back up, then quickly return the rubber cap fitted to the valve.
-Step 4: Remove steam
To remove air in a tire simply press on the valve body with your fingernail or use small tools to hold it until all the air is released.
Also known as van Sclaverand or France, this van is often found on high-end road bikes. The Presta valve is designed to be longer and narrower than the Schrader valve diameter, and has an external valve body protected by a valve cap, rather than being surrounded by a valve core.
-Step 1: Open the Presta valve
Carry the hood tower over the valve and place it in a safe place. Deep that, loosen the small brass bolt on the valve body, it won’t open completely but you can lift the valve core a little. To check that you have loosened the cover loosened enough, press on the valve body. If you could hear the air coming out in a powerful explosion you would have relaxed it enough.
-Step 2: Find out the recommended PSI
This is generally recommended pressure for your tires. They are clearly printed on the tire covering the recommended pressure range. Never go with a pressure lower than or above the recommended PSI limit.
-Step 3: Find a pump
Try to use a gas pump or maybe borrow a dedicated pump from a friend. You can also buy pumps from bicycle accessories stores.
To be able to pump on the Presta valve you need an adapter end from the Presta. This is a small hood that can screw onto the Presta vab essentially turns into a Schrader van. Some old bike pumps may require you to get a Presta-matching regulator. You can purchase this set from the repair shop. When using a gas pump, ask the waiter how to measure the pressure when pumping the tires to avoid the explosion of the tire, remember to check the tire pressure every time. Usually these pumps are under high pressure and you can cause your tires to explode at any moment.
If you are using a pump with 2 pumps then the smaller end is the Presta valve. A smart pump has an opening that automatically adjusts to the Presta valve. There is also a pump with an additional opening that requires you to water a rubber stopper inside to fit the Presta van. Remove the cover and find the rubber stopper inside so that it can fit the Presta valve. Remove the cover and find the rubber stopper. Smaller end fits on top of Presta valve.
-Step 4: inflate the tires
Perform the Presta valve opening by removing the valve cap cap and loosening the brass cap on the top of the valve. Place the pump nozzle on the valve. If there is a lever near the pump nozzle, make sure it is in the open position (parallel to the pump nozzle) when you place it in the valve; pull the lever down to the closed position (perpendicular to the pump nozzle) when it turns on. Keep one side on the pressure as you pump. Turn the lever over to unscrew and tighten the brass cap.
Step 5: Remove the tire cover with the Presta valve, open the brass cover and press on the tire valve body until all the air can escape.
3. Van Woods
Van Woods is also known as van Dunlop commonly used in Asia and Europe. It is the same size as the Schrader van, but uses the same mechanism as a Presta van. The pump is similar to the Presta valve.
