you know, I have no recollection of the technical aspect of Biopace, and there also very well may have been diff versions of biopace also.
What I do remember is having a real bugger of a problem with one knee on that trip, I even had to hang around at a provincial campground for a few days to let my knee recover so I could actually continue the trip. I also remember my legs not liking the oval thing, as I always found higher cadences to be so bouncy wouncy--but this is where it would be interesting to try them now, as Im certainly a better cyclist in terms of pedalling. Given so many top racers use it with great success, there has to be something to it, and it probably just takes a slight change of how one pedals.

re my bum knee--unfortunately I very much associate that with the Biopace rings, although to be fair that knee had had bings and bangs before 91 with skiing and motorcycling falls, so who knows. All I know is that to this day, and even more as I age, that knee grumbles at times, especially when I dont ride enough and or overdo it.
