This looks like a great low water Salt River Rig. Did you get those frame yokes from us, or did you copy them? I know that part is not rocket science, but I am impressed with the Clamp arangements that you made. I would not mind putting the idea on our pack cat/ fat cat photo album site, with a little description on how you did it.
We make tubes, and we encourage customers to do what they can for frames. In this way we get a lot of great ideas from folks that find it easy to innovate.
Thanks for considering this. If you do want to share that information with us, send it to my perosonal email email@example.com
