Is the small size difference significant? Will the headset fit? What’s your educated guess? Btw, I won’t buy anything based solely on your answer, I’ll be contacting WI soon.
Did you build this frame? 43.8mm is the unfinished size of the internal diameter. It is meant to be reamed to 43.95 after building.
It is very common to use a tapered steerer fork in a 44mm head tube and a number of headset brands make headset cups that will make it work. I use Cane Creek headsets for all of the frames that I build. You need an EC44/40 lower headset and a ZS44/28.6 upper headset.
