In the last decade, cycling more days than not, I think I’ve had three flat tyres or possibly four. Mind you, two of them have been on the same tube on the same wheel in the past two months, which is a bit more worrisome.
I decided to put a new tube in yesterday evening after having to walk to work. Hopefully that will sort it. Otherwise I’ll have to take a much closer look for the invisible cause of the tiny holes that have been releasing the air from my tyres.
