    Mystery frame assistance needed

    Hello All, I have a frame That I need some help identifying. I've done a fair bit of forum and web scouring, but decent close-ups of archive frames, and un-built frames seem rare.
    Size of mystery frame is C-T 20.5"
    Weight of mystery frame as-is (no shock as seen in photos) is 4 pounds 9 ounces (on my goofy USPS 10lb capacity scale)
    Guy I got it from said it is a 3" travel bike
    My thoughts; very similar to Sette Ace but... rear pivot on chainstay, extra brace in rear dropout to seatstay, and seat tube to seat stay pivot mounts inside seat stay instead of outside. So, Intebse spider? Tomac something?
    Another angle to my quesry is the very small crack at upper seat stay pivot point; How potentially serious would a failure here be while riding? Main goal here is to figure out if it's worth time/money to find a used shock and build this frame up for light duty xc/cummuting. Any thoughts are welcomed and appreciated.

    Looks like a "Horst link" design with the pivot in front of the dropout.

    You have a real crack there. Just imagine all the possibilities when the whole part collapses when you are riding.

    Basically what you have is a Sette Ace with a horst link swing arm. It is made by Astro Engineering (they make the Ace). The model is an SPSLN.

    I'm tempted to say that's just in the paint. It's a really bizarre direction for a crack to take from the pivot like that.

    Obviously the only way to know for sure is to buff the paint off and look.

    Take the pivot bolt out and see if the crack runs horizontally through the frame . .

    Thanks for the replies guys. One theory for the bizarre crack is ham-fisted pivot bearing install, and I agree, even though it was free, I thnk it will get stripped and recycled. the other frame I got with it seems to be a '05 or '06 KHS XC604. I'm pursuing a budget build in the "not too heavy" category. I'll get some pics of that in the next couple of says.
