I am attaching a few images of the complete bike. The handlebars seem really well-made, they are lightweight, and much stiffer compared to the handlebars I got with the Velobuild VB-R-177 (previous bike). Ergonomically, I went with 38cm width, which is narrower than what I had before and I like it so far, but there is no difference in feel compared to normal flat handlebars with an extra headset spacer. Aesthetically, I find them interesting as well and fast-looking, but I wouldn't buy them just for the looks... The minimalism of the regular non-raised design still has a place in my heart.
It looks like a relatively relaxed fit, but at the same time I am not an expert so I don't have much to say. I got to my current fit with similar tools that you used, but also through trial and error on the trainer and experience from my previous frame. My very general recommendation would be to i) copy and tweak the existing fit from your current road bike, if you have any, and ii) whenever you are unsure, try going with a conservative and average setup first (which I think you are already doing).
thank you for your detailed feedback. Actually this is going to be my first road bike. Of course I can borrow friend's bike and visit a shop to try as many bike as possibile, but I wanted to have the point of view of people who bought the same frame. I'm a XC rider and the riding postion is very different. For sure for my road bike Iìm not looking for an extreme postion, I'm not going to race it, but I wanna have it dialed the proper way. I'm sure 56 is the right size now and I'm going to order a 0 offeset seatport. The oly open point is stem lenght 90 or 100 mm.
