I tried one. Found I couldnt keep my eyes off my stem, so I took it off.

I recall that Bernard Hinault is using one.

I have used one but not as deformed as this. Seems like Wiggo was using one as well. I have used the Rotor Ring more, I think it works for me. That ring seems pretty extreme to me.

Obviously the patent on bio-pace chainrings has expired.

Is that a 38.3 or a 38.4?

Hehehe.... true... I have not tried those new brands but from looking at them the oval is different to biopace, biopace was a good idea that sucked in racing environments, did not work for racing, I used one for like a week...

The new ones since they look different they have to act different than biopace.

biopace rings seem much less extreme, but of course I appreciate your sense of history

Other companies made ovalized rings before Shimano...
