Watching Paris - Nice

And it looks like Bradley Wiggins is using an oval big crank ring on his bike. Any ideas? Has Biopace come back?

Wiggo uses O Symetric rings:

It's not uncommon in the modern peloton these days. Rotor Q-Rings are also popular.

That was what it was called. I keep telling all the kiddies that it was all the rage in the 90s until it wasn't any more.

I had a Biopace chainset, it was no better than a standard one. This explains why:

http://www.highpath.net/ says "Biopace-type rings: These gave Ovals a bad name in the 1980's because their crank offsets orientated them back-to-front on upright bicycles. This gave a higher gear to push through the dead-spots instead of a lower one, making matters worse, not better!"

I also thought this read 'watching Paris, Nice' i was most distressed to find out you ware talking about Wiggins' ring.
