Gravel bikes and BB drop, opinions?
With a hardtail, only the front compresses, so the effect will be about half that on the bb, as robertpb outlined. There are arguments for running relatively little bb drop on a gravel bike; Fork offset is the distance between the front axle and the steering axis of the fork. The diagram above shows how the front axle.

How far the bottom bracket is above the ground. Describes the same thing as bb drop, but varies depending on tyre choice, suspension sag and other factors. 70 is in the normal range for a road bike. It’s low enough to provide a low center of gravity yet it’s high enough to allow pedaling through corners without scraping a pedal..

Keep in mind, because the fork is on an angle, there’s a horizontal component to the increased axle to crown height. The bb drop is also influenced by the amount of travel on the suspension. So the bb drop tends to be lower on bigger travel bikes. The wheelbase gets longer because of the difference in fork offset and axle.

A greater bottom bracket drop lowers your centre of gravity and provides more stability, but that needs to be balanced against the need for pedal clearance. Bb drop seems to have settled at 7 cm for most road bikes. Almost every bike ever will have a bb below that line. A bigger drop lowers your centre of gravity, good for.

This shouldn't be a problem if your cranks are flat, but you can't guarantee that you won't be pedalling over bumpy ground. A bigger drop lowers your centre of gravity, good for cornering but less good for catching your pedals on the ground! The head tube and seat tube angles get slacker because the front of the bike gets taller..
