All the way home from, and some of the way to, work yesterday I was convinced one of my tyres was about to in flat. There's a strange little shimmy it does as the sidewalls flex because the pressure's dropped. However, both tyres remained resolutely pumped up for the whole of both journeys.
As I cycle down Palatine Road i have to cross over to get to my flat. On that side of the road, a short distance before my house, is a bus stop. Just after I passed it, as I was checking traffic and preparing to cross there was a shout and movement by it.
I slowed a bit more, and it became obvious what was going on. A guy was running down the street, pursued by a woman shouting "Thief!". I thought about it for a moment, then started checking the traffic to see how soon I could get across and start chasing the bag snatcher along the pavement.
Which was when my front tyre decided to puncture, with a distinct pop and dramatic hiss. I wasn't going to get very far with a useless front wheel and I'd not catch him on foot, so I could only watch as the sad little drama headed toward Lapwing Lane.
