I rounded some of my numbers above, which explains the very small difference. Glad I got that close though.

But how did you get that calculator to work given it asks for the SC Pulley in cog teeth?

You are computing a dimensionless number (ratio). As long as the units match up (teeth/teeth, circumference/circumference, etc), it will work.

Thought it might be that simple, but didn't want to assume. Thank you.

Well in that case my opening post is correct.
