Umm.. With a 12 tooth fixed wheel sprocket, I could follow the school
bus in the
displaced air return. I don't suppose the diesel smoke did my lungs
much good but this
was 1958 or thereabouts.

pedant ?

I'd have preferred a freewheel sprocket myself. I wouldn't fancy being
on a fixie in that situation, if the bus had come to quick stop.

At the time, I had the largest available front ring. 12 tooth did not
then come with a free wheel.
Stopping was never an issue but frost on the road and the vehicle going
too fast for my pedaling was dangerous:-(
