Trying to use it with Hope Hubs but can't seem to find any information about the pitch diameter and flange thingyum in the calculator, even when I get there directly from Hope's website.
ANyone help?

I think the wheelpro calc has standard Hope hubs in there. If not, it gives detailed instructions on how to measure them

The DT Swiss one seems to be very hit & miss at the moment.
Some days it has 'others' on the drop down menu for hubs, but at the moment that isn't happening.
Try the wheelpro one, if not you might have to resort to messuring everything out.

Thanks guys found the wheelpro one.
