Seeing as you asked…
Relying on cleats? Probably. But so what if I am?
You’re doing it wrong.
flat pedal specific technique.
No such thing; same technique.
DH riders must have moved over to clips as they must provide some benefit and more control in the air will be a good reason I’d bet.
To pedal harder on the flat sections, would be my bet.
I was working on table tops today, worked my way upto about 3ft, but the OP’s photo looks more than that.
Up to 3 ft? The OP’s photo looks like a drop, not a tabletop. Small drop, but it’d be silly to start with a large one. 😉
Looks to me like he’s got his weight off the back and pretty straight arms and very bent legs. With weight centered, there’d be better control on landing and some force going into the front wheel instead of it being light. Straighter legs would enable soaking up the landing by bending them, just like you do when you jump without a bike.
Might be fine for a small drop, but doing the same off a bigger one would magnify the errors & increase the crash potential – I know, I’ve been there 🙂
