There are still a lot of Biopace around, at about a one 10th of the price.
I appreciate the resurrection of these threads. My cannondale has biopace and I've been trying to read about it. I've had it for 4 years or so I guess and had it out on loan for about 3 of the 4. The dozen or so times I rode it, I couldnt even tell a difference. It took a guy out on a ride to tell me about it a week ago. How embarrasing not to know that about a bike you are riding lol. I've never felt a difference and that late 80's Cannondale Crit Series feels considerably faster than my 2009(i forget the actual year) Specialized Allez.
