It’d be cool to see one designed for our traditional Mtb Decks.
so it attaches at the tales rather than having bolts going through under where your feet are.
The axle offset on those is pretty significant.
What you really want to do I think is instead of having the two bushings in line with each other, bend it so that its like /\ but only maybe at 30 deg or so, and a bushing on either side. That way you can bring the axle up closer to the pivot axis a bit and I think the bushings would support each other better.

Where do we get them?

Like this?
above design also helps with this as the axel offset is only the width of the bushing.

I think that’s a lot closer to a normal offset.
Interesting concept. Baseplate would likely need to be two piece design, right? Maybe pivot cups on both sides for vibration dampening. Either way would reduce a lot of slop. Someone should test this design.

Some of those designs are Chris Chaputs work. Maybe @RipTideSports knows something about them
I just found them when I was looking on the internet for inspiration

This is my favorite of the old Chris Chaput experiments.

Where is the GoPro video of this bombing a hill?
Also with the new freebord generation we might have some new bindings to try out or at least the old ones being available again after the Kickstarter.
@moon Most of them went away for valid reasons like many of the iterations you can find at the Morro Bay Skateboard museum

A flexible deck will turn more when you load the deck. As the effective truck angle will be slightly higher when the deck flexes.
@RipTideSports Any comments on that?

Bushings do not have a lot to do with these questions since bushings are functionally dampening devices that restrict the movement of the hanger in relation to the base plate. A truck’s geometry determines it’s lean to turn ratio. A truck’s total range is from a neutral position to mechanical lock where the hanger crashes into the king pin. DKP’s can turn more than a TKP and a TKP turns more than a RKP for most commercially available trucks.
The easiest to understand is a RKP geometry: As the king pin approaches vertical, your lean goes up and your turn goes down. As the king pin approaches horizontal, your lean goes down and your turn goes up.
Since I have been working with @MoeStooge 3 Link trucks over the last year and have been computer modeling their potential, I have learned a lot of new things (I love when that happens). Being able to easily adjust the lean / turn ratio based on the track and your potential speed matched with the grip we are getting with widened pneumatic and rubber race wheels has opened up new world. Believe me, a high speed set up that turns a lot without much lean is a set up where the rider and board quickly part ways…

Anyone ever seen this specific adapter set before? It is called the “Waterborne Surf” and is attached between the truck and the deck and acts to make the board much more “surf” feeling with sharper turns for the same amount of lean. I don’t have any personal experience with it but the videos of people using it look interesting.

I road an inboard with one on it. Fun at low speed but kinda sketchy in general.

I dont know if any one mention this yet but more concave, I find helps a lot with quick turning especially on sidewalks and around people at low speeds. If you think about it you can put more pressure from your body weight on the edge of your deck without leaning nearly as much.
Also people say that aggressive concave hurts your feet but it does affect my feet at all. My legs get tired before my feet.
Here’s my deck for example. I wouldnt mind more concave tbh

Concave is like having a higher deck in only the places you need it.
I knew a rider who once tried to advocate for 2" concave, but I think that turned around when he actually made a board with it.

I am thinking the waterborne surf adapter may be a potential solution. I do not think a truck can do it all by itself even it is optimized. Just like truck movement is controlled with bushings, what would it be like if the left and right rotation of the waterborne adapter was also managed with a bushing on each side? Less resistance at first that quickly ramps up preventing a potentially dangerous oversteer scenario. Durometer could also be increased/decreased to further tune the characteristics. This would really increase your ability to turn without having to lean as much.
