I may have opined once or twice on this subject in the forum…
When I got a new gravel bike this year, my primary goal was a lower BB. My last frame was a Crux with a BB drop of 68 and, for me, it was noticeable. I ended up with an Aspero with a 76 bb drop and I know I made the right choice. My cornering has improved and I fell way more stable on the bike.
Many years ago when I was doing product development in the bike biz, I did a run of prototype CX frames from 853 steel. I dropped the BB and also extended the front end in order to run a shorter stem (sound familiar?). Those bikes were universally praised by everyone who got one….including a couple of hard core CX guys at different mags.
TL:DR - I’m all in on lower BB heights for both gravel and CX, but especially gravel. A case can be made for a higher BB for dedicated CX frames, but IMO, the near-always advantages of a lower BB (lower CH, more stability, better traction) outweigh the occasional advantages (pedal strikes, bunnyhops, etc) of a higher BB.
