Sembawang, 41 km Smell it! See it! That's right! Pollutant Standards Index is an almost good 56, and it remains so. Sunlight pours down from the clear blue sky through cotton ball white clouds, instead of being shrouded like a corpse in toxic grey ashes.
I cycle to the sea, well, the straits. And stop at a bar which hasn't opened yet (it is afternoon). She serves me a Coke anyway. I have the place all to myself, as staff arrive to start work.
After the ride, I find my tyre flat. What looks like the tip of a nail is stuck in the tyre, beside a knob. The metal didn't hit any knob, the knob didn't elevate the tyre over the tip. Somehow, the tip hit where the rubber meets the road, the point which would cause damage. In thousands of km riding on knobbies, I don't recall finding debris on knobs. Do knobs repel debris back onto the road or onto the tyre where it'd cause damage? Perhaps, it's more likely debris would miss knobs since a smaller surface area of a tyre is knobby?
