    In MTB terms its a 4 bar Horst linkage.

    How is it a four bar? there is only one pivot point at the BB. A four bar would have another pivot on the chain stay or seat stay. The is not a pivot at the top of the seat tube, it is a brace. Horst link simply refers to the placement of the pivot

    edit: is there a 2nd pivot at the rear wheel drop out? It is very hard to tell from the pics

    Yes. It's definitely not a single pivot design.

    There are pivots on the chain stay. The Horst link design is any that puts the rear dropout behind and above that pivot.

    No silly, we're having a barely distinguishably different technical discussion about rear suspension design. All that matters though is it feels squishy when you sit on it.

    I meant the "how is it 4 bar" part of the discussion. Geez.

    I'll admit that while having donated part of my brain to having kids normally makes me feel a little less sharp than I used to be, reading the stuff you post, Marc, and your dissection of the minutiae often makes my head spin.

    Then again, I have a cousin who is an engineer so I'm somewhat used to it.

    ...and a dishing tool, and a spoke tension measuring tool...

    Although I didn't rebuilt my entire wheel I did kinda mess with all the spoke tensions to try to get it as balanced and true as I could... it was a lot of fun and very interesting what I learned in the process - it's all a give and take between equal spoke tension and the different trues. You can't have it all with everything usually so you have to find a happy equilibrium.

    Park tool used to have this nifty excel spreadsheet on their site that made adjusting a wheel much easier to picture. I can't find the copy I thought I had on my pc... its not on their site anymore... bummer.

    I think that's a very astute (and accurate) observation.
