the bars on your MTB seem higher than I would set up my road, CX or gravel bike. I’m not sure the inboard bar ends are actually replicating being on the hoods.
I’ve worked on and ridden a couple of gravel events now (Dirty Reivers, Grinduro and some local Velotastic rides) and so many riders on drop bar bikes seem utterly terrified of descending.
Judging by my road club, roadies coming from road to gravel, rather than mountain bikers coming from mountain biking to gravel, tend to have that look. See also mud, off camber
