I did some research on it (Sheldon etc) and learned the principle behind it, and that it is apparently now pretty-well obsolete.
Apparently Shimano and a few others made them as well.
'Delie' is the only one of my machines so fitted, and I do suspect that it's one of the reasons why she is so easy to ride, esp on hills.
Anyone else using, or has used them? Opinions, please? And any advice...

They are quite popular (again).

(sorry for the blurry photo, must get a new one!)
I personally found that the oval rings made grinding up a hill fully loaded slightly easier, they are after all designed to work optimally at low revs. I generally seemed to be one sprocket lower down the block than with a comparable bike with round rings. As I don't spin much past 95-100 rpm I didn't find they adversely affected my pedaling at higher speeds.
So they must be some good as they've stayed on the bike for almost 30 years (gosh getting old...) but when they finally wear out, if I had to replace them with round rings due to unavailability I wouldn't be too sad about it.
