I rode a 100k perm on a rental Specialized Diverge Comp E5 (not a 2018, but it was definitely that level in the lineup - the nicest aluminum-frame one) -- seemed a perfectly reasonable bike for the job, although I didn't look at its detailed specifications.
I find a lightweight handlebar bag with lightweight contents is fine on a mid/high trail bike (you've seen my regular brevet bike; it's custom steel but NOT low trail).
