  • Can't see much from online images but the usual thing to change a pump from one valve type to the other is this. I'm guessing it is set for Shraeder at the moment? Undo the knurled piece where the valve goes in. There should be a rubber grommet affair with a big hole at one end and a smaller one at the other. For Presta small hole forwards. Refit the knurled bit. Again assumtion from the pictures. Put the lever parallel with the pump, push onto valve, lift lever then pump.

  • Im on my third one of these ,when they did work it took ages to pump up a tyre. Then after a while when using them the air came straight back out of the handle, so as soon as you stopped pumping all the air came right back out of the tyre . Luckly other friends have had pumps i could use to get me home .Maybe i was just unlucky :(
