Been using the bike for the past week with a very slow puncture ,been doing shift work so i didnt have time to sort it untill my day off .
Well … dug the tyre levers out got the tyre off the rim and found this !..and the valve core had also come away from the inner tube also, now my bike runs on spoked wheels and i was only having to put 5lb of pressure in the tyre each evening to get me too and from work .
