Ok I'm bored and I cleaned my shop up and rearranged things where I have a little more room. I'm going to try to do Antial's design. What I have come up with so far will be close. He had a solid tube on the bottom and twin tubes on the top. I am going to do twin tubes on the top and bottom. I ran into a kinda design problem right off the bat . On his there is really nothing to hold the back part of the chain stays. I'm going to do a curved tube around the back wheel that I have grown to love. I can still do his seatpost , but it will just come together at the top of the curved tube around the back tire. I'm just in the design stage and I need to run tomorrow and pick up more tubing. Its coming together. Here is what I have so far.
