    The inset tubes bend back to same width as the frame at the rear.

    Would one more bend have really blown the whole design and/or mfg process?

    Really?!?
    Really.

    To my knowledge, no custom box frame has three tubes that are all joined together at a single location where the sections of tubing have such complex curves. Keep in mind that that is one of the most stressed parts of the frame, and if the alignment isn't perfect, the whole frame will be off. I could see something like that being feasible if every frame was identical, but not for custom builds.

    toto,

    Why not see if Oracing would be willing to build frame with the same complex curves?

      That's surprising, given their experience, technology, and reputation they kindle via their marketing.

      I believe you, just surprised.

      (I'm being purely speculative, but I bet nothing is impossible, rather, impractical within a given set of business driven constraints!)

      I'm happy to be a guinea pig for any experiments in "single tube" designs, regardless.

        complex curves?? those are complex curves
        Anyway i don`t think they could do it, they are just a little company that dosen`t have enough money to buy a good bend machine , but Ti could buy it.

          They use their teeth, right? Even more impressive.

            i dont know how complex the curves are - its not as though the competing designs have dead straight, unbent tubes... anyway, surely they can get around this by using either a one piece backpost/seatrail or a one piece backpost/lower frame, and welding onto it as necessary. thats what would look better anyway

              NOO, now they don`t bend the tubes with their teeth, the dentist was too expensive, so they put their ingineer to work on a new tube bending system and as you can see the result is awesone, now they dosen`t need to go to the gym
