Does Sheldon recommend biopace ...
...chainrings for fixed gear bikes? I recall he wrote something but can't quite remember if he was a biospace proponent. Not incidentally, I put one (44t) on my bike yesterday and rode it around the block. No problems, though I haven't figured out (yet) how it's going to help. The ring looks cool nonetheless.
Anyway, just wondering if I'm doing myself any favors with this new chainring.
