Perplexing rear flatting issue. Submerged entire rear wheel - rim and tyre - in water and not a single bubble from anywhere at 60psi (G-one on converted rim) and yet it is virtually flat (under 20psi) after a 7-mile ride and a day sat outside the office. Have plugged a few holes and it had a fresh load of Stan's in after a recent issue. Plenty of life left in it I think, just very weird that I can't see where air is coming from. Ideas?
