I personally don't care for this design (too radical and "folding bike" style for me). I don't care for boring basic double triangle frames either, but I applaud you Mark for not only thinking outside the box, but spending the cash, and making it happen. Being in the frame industry myself, I see all kinds of requests for different things. It takes a lot to follow through on a project like this, between functional setbacks, strength concerns, load limits and weight distrbution.
Cheers to Mark for seeing it through and staying the course.
It sounds like it rides very well too, which was the whole point anyways...Mission Accomplished!
