Cyclists should be prepared to inflate the flat tire or simply bring it up to the recommended tire pressure settings. For this you need a bicycle pump.
This article will help you choose bicycle pumps so you can shop wisely.
Almost all bicycle hoses use Presta or Schrader valve stems. The third option – Dunlop, which is rare to find, is used on some international motorcycles.
Bicycle pumps can normally be used for any type of valve. When purchasing, note that cheaper pumps may require an adapter for one of the valve types. Most others adapt automatically. Presta and Schrader valves do not require adapters.
Floor Bicycle Pumps
They are ideal for use in garage and workshop.
Their difference is to ensure high throughput (in some models up to 10 bar) for different bicycle tires and to work under high pressure, which many small portable pumps can not.
Most of them have large, built-in sensors for convenient pressure monitoring.
Frame Bicycle Pumps
These pumps are best for racing bikes and are located directly on the bicycle frame (usually under the top tube), without the additional fasteners required for mini pumps.
They are bigger and heavier than most minipumps but work faster. Their large capacities (up to 160 psi) are designed to fill high-pressure tires used for racing bikes.
Sizes are S, M, L, etc. depending on the overall size of the frame (in centimeters) or the length of the top tube (in mm).
Make sure you know the size of the bike before you buy it.
Mini Bicycle Pumps
These small, lightweight pumps are a quick and easy solution for use in a home or on the road.
Most of them can be attached to the frame of the bicycle at different locations (some even fit under a bottle of water) using mounting hardware or a mounting strap.
Mountain bikers tend to store minipumps in a hydrated pack in a safe place and protect them from dirt.
Consider the pumping power when buying:
- Models up to 90 psi – for mountain bikes.
- Models up to 120 psi – for the fastest mountain bikes or comfortable bikes; for some road bikes.
- Models up to 160 psi are ideal for racing bikes.
Most minipumps are now delivered with an integrated hose. This convenient feature reduces the load on the valve stem, which can burst when carelessly handled using a standard rigid pump.
CO2 Bicycle Pumps
They provide a quick fix in a lightweight, minimalist version.
Popular with drivers and those who want to drive freely (they fit in your pocket).
The pump consists of a nozzle and a cartridge. Cartridges are disposable, only after use, the remaining CO2 evaporates after a few hours.
Repair or replace damaged tubes and replenish a portion of CO2. That’s enough for the rest of the journey. After returning home, purge all CO2 from the line with air.
- Size 16 g – best suited for a single-road tire with 700 c.
- Size 20 g – can fill a pair of tires with 700 c or a tire (26 “or 29”) of a mountain bike.
- Some nozzles have a shut-off valve to make the air filling more accurate.
- Some nozzles and cartridges have different threads. Therefore, make sure you receive a compatible set of replacement cartridges.
Tire pressure ranges
The correct tire pressure depends on the following factors: tire size and sidewall thickness, rider weight, driving conditions and much more. In general, fully inflated tires are best for flat surfaces. Somewhat incomplete tires – better for uneven roads or tracks.
Bar is a metric equivalent. Approximate recommended tire pressure range:
- Road bike: 5.5-9 bar (80-130 psi).
- Comfortable bike: 2,2-4,8 bar (35-70 psi).
- Mountain bike: 2.1-4.2 bar (30-60 psi).
