What's the difference between a Presta and a Schrader valve?
Presta valves are more slender and use a locknut instead of a spring.
They are normally used on road bikes because large holes greatly weaken the tires.
Presta valves need the small head unscrewed before they can be pumped.
Schrader valves are more robust and universally used.
They are easier to use since you just need to press it down with a depressor.
