It's funny how old things become new again:

I was watching television coverage of the Amgen Tour of California this year, when the Versus network did the funniest segment. They have these segments sprinkled throughout the telecast about riders and equipment, etc... and they had a story about the newest developments in professional cycling.

And what did they claim was the hottest new technology in the peleton?

You got it: oval chainrings!

They went on about how this innovation was the newest thing to hit cycling and how it would eventually trickle down to be equipped on the bikes owned by we mere mortals some day.

Hell... I was riding Biopace oval chainrings 25 years ago!
