Yes i got the T1550 GEN 2 in chameleon white in size 520.
Let me share my first impressions: Straight out of the box, the quality seems very good. The paint job is great, and the visible parts of the frame make a good impression. The build went smoothly, without any problems. In the first few meters, the build gives a very solid impression: nothing rattles, no noises from the bottom bracket, even under heavy load. In the chosen size(56cm stack), I feel comfortable. It feels noticeably more compact and aerodynamic than my old 58cm frame. The bike rides very well. As mentioned by others, it is very stiff. When ordering, I was concerned that it might be too stiff, even uncomfortable. After three 100km rides, I cannot confirm this. I don't feel uncomfortable at all.
Overall i already love the bike.
