Flat front gear
Is it a distortion of the photo, or is that front large cog look flattened out?

That does look funny, but I'd guess it's just a photographic artifact from compression or whatever.
The biopace chainrings were odd enough; I don't think anyone would like an octagonal one.....

Hehe- a highly technical article that's way beyond my limited mathematical and engineering abilities. The idea is one of those that "seems" sound; yet as the article notes, Biopace was essentially a disaster. The other designs just seem to my limited understanding to be variations on a theme.
The primary complaint from riders, as I recall (and I'm old enough to recall) was that they "felt funny".
I'll reserve judgement until we see if anyone buys this new effort.

I have some of the original biopace chain rings on my really old mountain bike. I never could feel any difference but I rarely ride that bike.

i used to run a 50 bio pace i believe it was a 2nd gen. i could notice a difference on that big of a ring but on the smaller ones its hard to tell. To each their own i guess
