This is a dumb question, but when it says on the description on Velobuild that the headset is 1-1/2" top and down, does this mean the fork is 1.5" in diameter? I was thinking about getting an FSA SMR stem and handlebar but I think they are only available for forks that are 1-1/8" in diameter. Thanks in advance!

Edit: Found that the fork is 1-1/8" from this video here:

I couldn't find any threads on here about this bike so curious if anyone has any experience building one? I am particularly interested in the tire clearance. Carbonda has on their website that it's 25mm but wasn't sure if that was measured or labeled width. Would love any thoughts if anyone has experience with this frame.
