Odd BCD.
Help
I bought these chain rings and they have an odd BCD.
They have 60 mm between holes
What are they?.
The difference between holes for 110BCD is 65mm.

Sheldon's crib sheet has the Avocet Triple inner as a 102 BCD with 60.0mm between adjacent holes.

You might have covered it up with the ruler but there should be a tooth count stamping that looks like this: ~36
That’s the logotype for Ofmega and Avocet chainrings. They make 144mm bcd main and middle double chainrings and 102mm and 74mm bcd inners for its triples.
