Tires can make a huge difference...
... And keeping the PSI topped up helps too..
BTW changing threadless Fork stems are easy, ++ for touring bags on the handlebars
it is also practical to have a separate bar for the widgets, and the bag mount ,
that 2 stacked stems can offer .. for your handlebars
a new stem longer and horizontal extension.
and flip the one you have and put it underneath, , like a clamp-on spacer..
looks like you have enough steerer tube ...
