There are considerable differences in the function and design of pump heads from different manufacturers. In general, there are two types of pump heads: screw heads and plug-in heads. The latter are widespread and more commonly used, while the screw-on version is less common. The pump heads of common floor pumps fit both Sclaverand and Schrader valves. Sclaverand valves, also known as Presta valves, are used today in almost all types of bikes such as road bikes, gravel bikes, mountain bikes and pedelecs. Schrader valves (car valves) are practical for checking the tyre pressure of motorbikes or cars at home.
A lever is used to attach the attached pump heads, which can be used to open and close the rubber seal. Depending on whether the pump head has one or two openings for different valve types, it is either tilted or swivelled. Both variants have their advantages and disadvantages: Operation is simple, but with the tilting lever there is a risk of getting your fingers caught like in a mousetrap. With the swivelling version, it can get a little tight between the spokes of the wheel. The safest and most effective pump head is the screw head. Tip: Always check that the valve insert is firmly seated before fitting, as it can come loose when unscrewing and the air will then escape.
For our comprehensive floor pump test from TOUR 02/2023, we researched all the manufacturers tested to find out which bicycle floor pump spare parts they stock in their spare parts warehouses. The good news is that almost all manufacturers offer the heavily used pump head as an individual part for purchase. In addition, some manufacturers also offer other individual parts such as hoses or rubber seals.
Our sister magazine TOUR has tested the bicycle air pumps mentioned above. You can read the results in the article: Floor pumps up to 60 euros: 10 current models in the test.
