Bike Pumps Guide

 

Bike Pumps Guide

Bike pumps come in many shapes and sizes and are designed for different purposes. We’ll cover all the different types of pump in the guide, but first let’s take a look at some things that are common to all bike pumps.


What to look for

Valve Type

There are two main valve types used for cycling. Many bike pumps are suitable for both types, but some will only fit one type of valve, so it’s best to know which type you need before you buy.

Schrader valves are the same type of valve that you find on cars. This valve type is usually found on kids bikes as well as more affordable mountain and hybrid bikes. A Schrader type valve is also used for air sprung shocks and forks.

Presta valves are cycling specific valves. You’ll find these valves on road bikes as well as high-end mountain and hybrid bikes. Most tubeless valves are Presta valves.

Tyre Pressure

The perfect air pressure for your tyres will depend on the volume of the tyre. Narrow road tyres need a much higher air pressure than wide mountain bike tyres. The maximum air pressure for a tyre will be written on the side wall of the tyre.

Pumps are rated up to a specific air pressure. You’ll need a higher-pressure pump for road bike tyres than for MTB tyres. Air pressure is measured in PSI (Pounds per Square Inch).

Types of Pump

Floor Pumps

Floor pumps make pumping up tyres easy. Also known as track pumps, they sit on the floor with a footrest and grips for both hands, so you can add a lot of air to your tyres with each stroke. Most have a dual valve head so you can easily switch between Presta and Schrader valves without making any adjustments. Floor pumps are perfect for the home workshop but are too big to carry on a ride.

Hand Pumps

Hand pumps or mini pumps are small enough to fit in your bag or attach to the frame of your bike. Perfect for fixing puncture you can carry a hand pump with you wherever you go. These pumps come in many sizes. Smaller ones are easy to carry but larger ones make pumping up your tyres easier. Some hand pumps feature a hose that makes it easier to pump your tyres up. Most hand pumps have a head that can easily be adjusted to work with both valve types.

Cartridge Pumps

Cartridge pumps or CO2 inflators are a valve head that connects to a CO2 cartridge. Sometimes these are combined with hand pumps. You can use CO2 inflators to pump your tyres up quickly or even seat tubeless tyres. You’ll need to carry spare cartridges with you to use them on a ride. We sell CO2 cartridges in our physical shops but they're not available to buy at Tredz online.

Shock Pumps

You’ll need a shock pump to adjust the air pressure in air sprung suspension forks and shocks. Suspension uses very high air pressures so a bike pump for tyres isn’t an option. Shock pumps are quite small as the volume is much lower than a bike tyre. The pressure gauge allows you to be very accurate with the air pressure in your fork or shock. All shock pumps use the same type of valve, so it is easy to switch between brands.

Tubeless Inflators

Seating tubeless tyres on the rim can be challenging with only a floor pump. This is because you can’t get the air in quickly enough to make a seal between the tyre and wheel rim. Tubeless inflators have a tank that you fill with air from a track pump, then release it into the tyre all in one go. This seats the tyre properly on the rim. Some tubeless inflators are combined with a floor pump.
