I have them on several bikes since those bikes originally came with them. I can't tell the difference.

That's certainly been my experience. I find them much easier on the knees. They're on the bike I ride most often and will go on the next build as well.

Well, hell - I didn't notice the date of Miele Man's comment above. Oh well, everybody goofs now and again . . . .

Doesn't change the fact they are easier on old, tired knees.

The few times I rode them, 35 years ago now, I felt like their effect was almost random. Sometimes, at some particular combination of grade, gear, wind, cadence, effort, fitness, weather, phase of the moon, whatever, they pretty obviously made me feel like a better rider. Change anything, even 5 minutes later, and they felt like oatmeal.

Mostly, I couldn't tell one way or the other.

Wouldn't seek 'em out, wouldn't take' em off.

I still have Biopace on a couple of my bikes. Those are the original type of Biopace. I also have a few Biopac rings in my stash in case I ever wear out the ones on those bikes.
