I'm headed to Sea Otter this spring, debating taking "the long way"... 2-3 days ride, off road, if possible, from SFO. Any suggestions?

Hi, I'm piecing together a new exploration/bikepacking bike, and starting with an Element 29 (Element | Rocky Mountain Bicycles)

If you were to spec the ultimate trail slaying adventure bike, what would it look like?

I don't want any funky bars (jones loop bars etc) because I want to confidently ride this on any trail, as it were a normal e29. Full 780mm bars...

Wheels? Tires? Widgets? Drivetrain? Gearing? Will be sporting full frame / seat/ bar bags when necessary.

Most bomber / rebuildable hubs?

I have plenty of personal opinions, but want to crowd source some ideas!
