I've interviewed bicyclists far and wide and never found anyone who has ever seen an elliptical oil
ring on the road, much less someone who had any idea of how they get there. They are thin elliptical
rings with a major to minor diameter of about pi:1 and between 20mm and 200mm long, the long axis in
line with traffic.
There WILL be a quiz!
Where do you find them and how are they made?
