His screen name is C-27,I think he is on the sponsor page.
Cannodale27 is his s/n. It does sound like you've lost your nitrogen charge. On both at the same time seems odd, but that's what it is. You could take them somewhere locally, but you never know what you'll get. If they just recharge, the probelm is still there, you've got a seal leaking. C27 has the best prices with great service. I highly recommend him.
