Anyone else use Biopace inner ring for climbing?
I've been running a 110/74 BCD triple (pulled off an old MTB) as a compact double on my road bike for the last few years with 34x50 round rings. But I hardly ever use the 34 around home (gently rolling farmland). The crank originally came with 28x38x48 Biopace rings and I still have them. So what I did last week is swap the 34 round for a 38 Biopace. And I like it so far. I can't spin really fast on that ring, but if I'm spinning that fast, I should be on the big ring anyway. On the short hills I've ridden so far, I seem to ride the same cog I would on the 34. I haven't been able to see how it feels on long climbs, but I'll be riding Horribly Hilly Hundreds in June and that should be a good test.

My first road bike had biopace on it. I was told that it was a gimmick and that it didn't really help at all. I don't know if that's true or not, but I never noticed a difference between it and the round chainrings on the bike I got after that.
