Does anyone have a good stem calculator recommendation? I used to use the brightspoke one, but it doesn't look like it is available anymore .

I'm trying to match my position on one bike to another. I've got my fit dialed in on the one, but the other has slightly different geometry (HT angle and length), and I was looking for a calculator to help figure out what stem length/rise would get me in the ballpark.

Anyone have a good recommendations?
