@lnlyisol asks:
I'd just turned to head home, when I thought "That sounds funny馃"
I stopped & found my front tyre deflated. The noise was different enough to alert me 馃く
Q2. My thoughts were:
1. Is distance from home related to likelihood of a problem?
2. Can other problems be picked up from subtle clues?
3. People with musical training, can you tell cadence/speed by listening to the frequency of pedaling, or the sound of the hub?
