Anybody got a Biopace 38T chainring in very good or (hey let's be realistic) good condition for sale?
I think it would need to be a Biopace SG variant, as I understand the pattern changed and I have brand new 48T and 28T SG ones to complete the set.
If anyone can enlighten me as to how the pattern changed, and why, I'm all years (or knees).
Cheers
Steven
