I awoke this morning to find the rear tyre on the fixie was completely flat, "a slow one" I thought.
Tyre off and tube out, no thorns or glass in the tyres, no visable pinch flats, nowt
I inflate the tube to see if it was the valve getting knocked open, then I discover that the valve was ripped half way out.
I shouldnt have gone 40 yards in that state, let alone 40 miles, I must have pleased the Valkeries or something.
