Many bike pumps have an adjustable nozzle that can accomodate either a Presta or a Schrader valve. That way, you can fill up any type of bike tube.

Difficulty: Moderately Easy

Instructions

Step 1

Start with the pump in Presta valve mode. Presta valves are the skinnier of the two valve types.
Step 2

Unscrew the top cap of the nozzle.
Step 3

Tap the pump gently so that a flexible rubber tube and a hard plastic tube come out of the nozzle.
Step 4

Flip the plastic piece upside-down so that the pointed end faces out of the nozzle. Then slide this piece back into the nozzle opening.
Step 5

Flip the rubber piece so that the end with the larger donut hole faces up, and slide it into the nozzle on top of the plastic piece.
Step 6

Screw the top cap back on and pump up a Schrader valve.
