Instructions

  1. 1

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

  2. 2

    Unscrew the top cap of the nozzle.

  3. 3

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

  4. 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.

  5. 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.

  6. 6

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

Tips and warnings

  • Follow the above steps backward to change the pump from Schrader to Presta.
