I did more searching and there appears to be 3 different brands of the same fork. HASSNS, LUTU, and Race Works. None of the listings show what the fork/wheel offset is.
I tried to contact the "Beautiful Sheep Store" Baaa, what a name for a store. (LOL), but for some unknown reason, I can't get a link to work to message them.
(This is one reason I went with a 29er hartail as my suspended gravel grinder, in order to keep the frame geometry correct and not lift up the front of the frame.)
