Chris,
Did I say I had a beef? No. I had a question. An honest one.

THANKS. You helped me find my mistake.
I was mis-reading their diagram of how to measure the flange distance (different calculators use different measurements, so I had a lot going on in my head at the time).

This is the DT Swiss way (most common).



I totally mis-read it, and was entering the measurement as if I was using the Sapim calculator (which asks for the distance from the axle locknut, not the hub center).

This is Sapim's way (uncommon) of doing it.


Sapim also calculates ERD using rim thickness and ID instead of simply inputting the standard ERD (much easier to measure), but that is immaterial, if weird.

So, my bad. Seems OK now and after changing my inputs I got the same output as BicycleTricycle.

Ya, I screwed that up the first time I used it as well.
