I have a Norco Mountaineer SL. It has a schrader valve and I am trying to inflate the tyres using https://www.amazon.ca/Crank-Brothers-16304-Sapphire-Silver/dp/B07K4PLWKW/
I seem to have set it up correctly for schrader valve. The air comes out of the pump head when I pump it. It seems to adjust on the bike valve fine. I then lock it and try to start pumping. The gauge moved the first time I pump and then remains at the same pressure. The air does not get into the tire remains stuck in the head/pipe of the pump and it then gets squeezed out when unplug it from the bike valve. How do I fix it?
I have tried moving the rubbers in the head of the pump but it seems to be squeezing air out just fine. I am not sure why is it not getting into the tyre AT ALL (Tried both tyres)
