Took wheel in to dealer for dismount, the t valve had only one seal, dealer was concerned so i called cyclemax and they said it works that way but dealer used another seal. So it goes rubber seal on outside of wheel, then rim then rubber seal. When i got home i had a clearance problem using a normal air chuck so i had to grind off the metal lip that held the o.e. plastic clip that holds on the valve stem retainer. Did you grind off the metal lip with your stems?
