Looking to change BOTH chain rings on my Biospace crank.
Any idea which make and sizes are available?

I'm not sure about yours, but I believe mine are 110mm (of course mine is a triple), I would measure before . . . using Sheldon's technique.

Do you want round, or are you just replacing worn-out rings? BP rings are readily available. I might even have some I'd sell cheap.

You should specify whether or not you want biopace chainrings or just regular round rings becuase they'll both work.

yea, I believe you can put any chainring with the same bolt pattern on that crank. I had a Biiopace way back when and when I needed a smaller inner ring, I just put a round one on.
