I don't have any real info to add, just that I went through the same thing when I was researching gravel bikes, I just think the Grevil is so cool. I ended up deciding that there were no brands that are well-loved by ChinerTown that make it, there's no real reviews on the frame, and it's often a bad idea to buy frame that are direct copy of another (because they may not have done Engineering, just copy the outer geometry and thickness, they may not know the actual layup schedule and material spec). Too much risk for me, so I went for a Carbonda.
