Bike Pump Guide: Presta vs Schrader vs Dunlop Valves
What bike pump for what valve?
The right bike pump depends on your tire valve type. Most bikes use one of three valves: Presta (common on road and many higher-pressure tires), Schrader (common on mountain bikes and many everyday bikes), or Dunlop/Woods (seen on some city and European bikes). Matching the pump head to the valve prevents air leaks, makes inflation faster, and helps avoid bending delicate valve stems.
Presta valve: what pump works best?
Presta valves are narrower and have a small locknut at the tip. Use a pump with a Presta-compatible head or a dual-head (Presta/Schrader) design. Before pumping, unscrew the small tip nut a few turns and briefly press it to “burp” the valve; then attach the pump and inflate. Many floor pumps and mini pumps include a reversible gasket or a lever-style head that switches between valve types.
Schrader valve: which pump should you use?
Schrader valves look like car tire valves and are wider than Presta. Most standard floor pumps, many mini pumps, and air compressors work with Schrader by default. If your pump is Presta-only, a simple Presta-to-Schrader adapter can let you use a Schrader pump head on a Presta tube, but not the other way around.
Dunlop/Woods valve: what are your options?
Dunlop valves often inflate with Presta-compatible pump heads, but compatibility varies by pump and valve core style. If the head won’t seal well, a small valve adapter is usually the easiest fix. For frequent use, choose a dual-valve floor pump that explicitly lists Dunlop support.
Quick tip: choose the easiest “universal” pump
If you own multiple bikes (or family bikes), a floor pump with a true dual head or an auto-select head is the simplest choice. Pairing it with a built-in gauge helps you reach the correct PSI without guesswork.

FAQ
How do I tell if my valve is Presta or Schrader?
Presta is skinny with a small screw-up tip nut, while Schrader is wider and looks like a car tire valve with a spring-loaded pin in the center. If the rim hole is larger and the valve body is thick, it’s usually Schrader.
