Just a heads up for who's interested: don't underestimate the importance of tire pressure on comfort and safety. There are several online tools for choosing the best tire pressure according to different parameters. At the link you find the one by Silca that is highly regarded.

As gravel bikes are generally rigid and rely on the tires to attenuate vibrations and absorb impacts, the correct pressure is key. I hope this could be useful to someone, I will add it to the sidebar.
