I’ve had double bike failure.
I thought I’d resolved an issue that arose with my fixie on Saturday, but the grinding whenever I put power down indicated quite emphatically that it was still very much present.
So I doubled back to collect my singlespeed. The tyres needed inflating, and somehow I’ve managed to remove the valve core on the rear and it’s not proved an easy thing to put back.
All rather frustrating, and means I’m immobile, short of driving across which I’m not keen to do.
