Have this pump with the ‘EVA’ head as shown. Fine on presta but can’t work out how it can possibly work on schraeder – nothing there to push the pin down.

Any clues?

Normally you take the insides out of the head and swap them round. Not sure about this one as I haven’t seen it in the flesh.

It works without adjustment, just try it 😀

Mine absolutely does NOT work without adjustment – no about of pushing it on and pumping inflates a schraeder tyre and looking into the head there’s nothing to push down the valve so i can’t see how it can work. Is there any part that could have fallen out?

Must have, mine works perfectly on presta. Press the presta valve down briefly before inflation to make sure its not sticky.

Bigdug it needs to work on schraeder not presta.

open up and flip around the insides for schraeder, if it’s not immediately obvious to you(which it should be), you’ll get it eventually.. just get yourself some presta tubes though, schraeder values are shit if you ask me.

You’ll need a tractor pump for Schraeder valves surely?

Just looked at mine. The rennkompressor doesn’t have a pin which opens a schraeder valve, it just uses air pressure.

Tried that – there are not bits to flip round.

I agree – unfortunately can’t get them for the tyres on the car or the Brompton.

Does that work on Schraeder? I’ve tried the SKS on both the car and Brommie tyres and the pressure guage just goes up to over 100psi in a couple of pumps but no air ever gets in the tyre.

(sorry, can’t help with the car)

Yes, it does work. I tested mine before posting to be sure.
