Bad week last week:
2 off - split in the inner tube. These are the sort of fast failures characterised by a loud bang, or at least an evident psshht sound. Strangely, both happened with the bike in the bike shed at work, i.e. it was OK when I wheeled it in, but flat and could not pump any air into it when I returned. I would assume sabotage or wheel / tyre defect, only it was different bikes in different bike sheds in different cities. And as far as I know, I'm the only one who can access both.
1 off - failed puncture repair under pressure. Rough canal towpath taken at speed caused the failure of the vulcanized joint.
1 off - pinch puncture. Surprised to see the snake bite, as I had pumped the tyre up only the night before, so there should have been enough air in it.
1 off - valve leaking - yes one of the screw-in continental tubes. Why?
1 off flat, but pumped up the inner tube, and cannot find a leak. Strange, as it was a fast puncture - full to flat in less than 24 hours.
And didn't come at a good time either. One was the rear wheel of a hub-geared bike. Couldn't undo the nut, so had to take it home on the train. One was when I had a train to catch. The puncture and replacement caused me to miss the train by 4 mins, and had to wait an hour for the next. Couldn't ride any further, as the another puncture occurred en route. 1 flat tyre and no spare inner tube. And on Friday, came back to my bike to find two flat wheels.
This week has been better.
