First real ride yesterday on a 3h winter ride
I found to be very fast and silent, like riding on a magic carpet. I was very happy

However feeling is not reactive, and frame has lateral flex specially on the front end. But so far I did not notice this negatively when cornering, could be positive? (like motogp bikes)
So no good for sprints but very good for maintaining high speeds with low effort.
Big part of this I assume is because of the wheels, I have the new Schwalbe G one pros in 50mm mounted on 30mm inner width rims and 45mm profile
Definitively not 50mm clearance on the rear, and you can suffer with mud. The wheel will roll, but the mud will build on the chainstay and will come to the chainring and transmission.
Finally after washing the bike I found water on the storage box, I think I will make a drill and possibly removing one of the walls to make box bigger
Edit: I’m 183cm tall and seat height is 79cm, and frame size L with 80mm stem is perfect
