Some time ago I bought a twin head fitting for my track pump Which works fine on the schrader valve. But on the presta valve the head it tips over so as fast as I pump air in it come back out Which I find somewhat demoralising! Though some inner tubes it doesn't seem to lose as much pressure when I inflate the tube I would like some advice on which other twin head fitting might help me get over this problem Thanks all
