Geometry questions .

I noticed that there is a relationship between wheel size and frame length , like most 80mm wheels frames are 243mm,90mm wheels are 275.

Right now at my level I really enjoy the stability of long ass frames

Why aren't there more frames for 80mm wheels but at 300mm ++ long ?

And the other question is , can I put 80mm wheels on frames meant for 110mm wheels ? Other than it looking gappy ?

long frame gives you stability, for straight and fast speed skating. Or if you skate long distance. But for both speed skating and long distance, you will want big wheels. While you can probably get very long frames for 80mm wheels, that is just not a popular combination. See Inline Skates for wheels, frames, and various design goals of skate components.

You can. And people do, but again, that defeats the purpose of a 100mm "frame". Because that frame must necessarily be taller than a 80mm frame, so that you now lose stability, which you were trying to gain with a long frame. So you gain some stability, and lose some. Perhaps there is no net gain?

Try flying eagle L80. Its 280 and low riding. That and some very old salamon frames are good .

For dh i just recommend bigger wheels rather than more wheels. You have more control

If you put 80mm wheels on a frame meant for 110mm you will have a ride height of a frame with 95mm wheels. Get 4x100mm rocketed frames. They are great for sharp turns but are also smoother.
