Well....

While building my seat some questions pop up.
As with every kind of wing, curves generate faster airflow and as such, less pressure at the curved part.

I see many seats with veeeeery nice curves (aus230, I love yours! ), but I wonder how these curves influence speed and downforce.

2 specific (closely related?) things I have in mind:

1. At 70kph, the curved seat could/would create under-pressure between ground & seat that it might pull the seat down, with extra load on rear axes?
If you 're chasing the wind in soft sand, wouldn't it pull you deeper into the sand, increasing drag on the wheels and reducing speed?
Do we want it? Is there a benefit in doing this?

2. As with any kind of surfing (I used to build boards), release of fluids (like air) is quite important. The rear part of many boards are built specifically to allow the water to release easily. If it's not, your board is sucked into the water and slowed down until the water manages to get of.
Reflecting this onto seat-form, it appears that few seats take this into account, letting the airflow just following the whole entire shape until ...

Imagine a sailboat having a rear end just like the front, the aft would get sucked down and speed would be totally fubar.

Look at the Iron Duck

And GreenBird

and its predecessors...


They all have a rear which allows easy air-release.
Why not look for an option to try this in Cl5?
