In the event of loss of tire pressure, have a bicycle pump at hand is always life-saving. A little re-inflation and we're off again. The pump is also essential in the repair of a puncture. It turns out to be a practical everyday tool. It makes it possible to ensure that you drive with tires that are always correctly inflated. To avoid any inconvenience on the road, find out all about this essential bike accessory.
It is important to take into account certain criteria to find the right model of bicycle pump for your needs. Among them, the compatibility of the valve, the lightness, or the precision of the pump. It will also be necessary to take into account the situation in which it will be used. Here are just a few tips to help you.
This inflation accessory uses Boyle’s law to ensure the transfer of air in the tires of a bicycle. For the operation to work properly, the cyclist must bind the nozzle of the pump to the valve of the tire. The air is then routed to the tire thanks to this valve and according to the repeated movements carried out.ar the user.
To better understand the functioning of the bicycle pump, it is necessary to know first of all that most pumps are equipped with a manual piston. When there is a suction action, this piston traps air in the chamber using a valve. When there is an action of expiration, the piston will bring the air towards the tire or the inner tube of the tire. This movement is repeated until the ideal pressure is obtained to inflate the tire.
Before choosing your bicycle pump, it is essential, as with all equipment, to always ensure that it is compatible with your equipment.
It's mostly about valve compatibility. Two types of valves are generally used: the Presta valve and the Schrader valve.
The Presta valve is mainly found on road bikes. It can also equip some tubeless mountain bikes. The Schrader valve is more generally found on mountain bikes. It is similar to the valves fitted to car tires.

Bike pumps offer different inflation pressure capacities, so be sure to choose a pump that can give you a higher capacity than the pressure you need for your tyres. This capacity is much greater with a foot pump.
A foot pump is more practical since it will allow you to achieve this higher pressure with minimal effort. With a hand pump, this will require more time and energy. Choose the type of pump that is best suited to the situation.
A hand pump is a small accessory that allows you to inflate a bicycle tire. However, with hand pumps it is quite difficult to achieve the XNUMX or XNUMX bars needed for a comfortable and safe bike ride.
Small and light, the mini pump slips easily into the jersey pocket or attaches to your bike. It is easy to carry during your bike rides.
The hand pump is considered a backup inflation device. It allows you to inflate a repaired or replaced inner tube after a puncture. These models of bicycle pumps are more particularly recommended for emergency repairs.
Typically one achieves close to XNUMX to XNUMX bars with a hand pump. But some manufacturers have developed products capable of blowing up to XNUMX bars with a hand pump. THE bud get from this type of pumps varies from about teneuro à more than XNUMX€. The price of a bicycle hand pump varies according to the materials used and the features offered.
Some hand pumps have a pressure gauge, which allows you to know the pressure in the tire as it goes. This pressure gauge can be digital, which increases its precision.
Some hand pumps are made of plastic, others of aluminum or carbon. The weight has an impact on the resistance of your pump. An aluminum hand pump deforms and heats up less than a plastic one. It also has a longer lifespan.
The hand pump shows its limits when it comes to reaching a pressure of XNUMX bars in the tires. There foot pump then proves to be an interesting alternative.
Thanks to foot pumps, it is faster to inflate a road bike tire. This is the ideal inflation accessory.
The prices for these accessories range from XNUMX€ to over XNUMX€. This discrepancy can again be explained par the options offered par the manufacturers. According to the bud get dedicated, the pressure gauge will be more reliable, the life of the tips and components more or less.
Choose aluminum materials over plastic for a longer pump life.
Some floor pump models are also compatible with several valves. It can be practical to have only one pump for all your bikes.
The precision of the bicycle pump is also one of the factors not to be overlooked in your choice. Indeed, having the right pressure in your tires is essential for the smooth running of your outings. When choosing your pump, always prefer a model that can tell you the exact pressure you give when inflating.
Certain hand and foot pumps have needle gauges to see the tire pressure. These gauges are also available on hand pump models. It is also possible to equip independent pressure gauges. For a much more precise reading, it is advisable to use an electronic pressure gauge.
The COXNUMX inflators allow very rapid inflation. They are an alternative to the hand pump during your bike rides. It is also easier to achieve the correct pressure with this inflation device.
They are light equipment and even smaller than a traditional bicycle pump that is easy to transport in a handlebar bag to use it in case of the unexpected. This makes it possible to reinflate a tire fairly quickly and without having to provide too much effort.
One of the limitations of inflating with a COXNUMX inflator is that in the event of multiple punctures, you must have several cartridges of compressed air with you.
La COXNUMX cartridge should be used only when necessary. Unlike the nitrogen molecule found in the air supplied par a bicycle pump, the CXNUMX molecule would tend to pass more through the latex or rubber, which would lead to a loss of tire pressure.
