Well I think it looked better in my mind. It's another twin seat tube bicycle, only now I'm adding 2x (1/2") down tubes, and 2x (7/16") top tubes and stays.
One problem I have is how I'm going to add a front deraileur. Suntour used to make a front deraileur that used to bolt on like brake levers with the strap. I could forget the strap and bolt it directly to the tube.

What about a braze on?
The problem starts with the twin seat tubes. A single seat tube leaves 19.7mm from the edge of the tube to the bottom bracket face. When construct the twin tube you take up the space leaving 8.6mm. You would never be able to adjust the der to shift down to the small ring. I could modify one, but then it would have to be behind the seat tube a bit. Now you can see the problem with that. I might just go with a curved seat tube.
Why not make a normal seat tube?
Problem solved!
End of conversation!
Where's my Bones, Thug's, & Gravel bike?
If I made a frame with a regular seat tube, then that would mean I'm working on your frame.
However it's getting late fast. I might have to scrap experimentation and make my cross frame, then your Gravel bike.
Just make it a single speed, forget about those deraileur thingys.
Got a split tube SS
