Explosion!

One job always leads to another. Then another. I got a puncture in Saturday when I went for a ride in the rain. It got me home, but went flat shortly after. So I fixed it today. I put in a new inner tube and inflated it to 80psi. I turned my back and without warning the whole wheel exploded with a mighty bang. My ears were ringing for a while, I can tell you. So I had to head to Halfords for a new one. Still. All done now. This one has some tread on it. T’other one was nigh on bald.
