 I most definitely was. The Superco Silencer was so damn sexy I just couldn't resist.

 Not yet, I'm hoping to build a couple more first.

 The main pivot shell is indeed an 83mm BB shell. The bearings and cups are a pair of modified profile BB cups machined down a little. These work well and are super bomb proof (4 bearings!). The pivot is a hollow aluminum shaft (6061) that is stepped on the idler side to fit through the bearing and swingarm.

 The only problem with the rod ends is that they have an ever so slight amount of play, maybe 1-2 thousands each. I'll probably do away with the rod ends on the next prototype because of this and the fact that they aren't that light.

 The total cost for all of the raw materials and hardware was about $450, that does not include the rear shock.

 Hi,
Here is a great website for hardware: http://www.mcmaster.com/#rod-ends/=c81w0o
I used one left-hand thread and one right hand thread heim joint fastened to the aluminum rod. You can also order reverse hand taps on mcmaster. I used a 3/8 x 24 male rod end rated at approx. 3k pounds each in tension or compression. If the rod has a length to diameter ratio of 10:1, you will want to use an engineering theory to calculate buckling (let me know if you need help).

 The last time I weighed it it came just over 40lbs.
The next prototype will use thinner material.

 Work it ride like a cloud and super smooth even on rough landing!

 I'm talking with a friend about making a race day bike with essentially the same design but a Ti front triangle and an aluminum swingarm. He was the Ti welder for Marin Bikes during the 90's and is currently a machinist at a global aerospace company. We are going to work on the design a bit and then build at least a few more. We'll see where it takes us.

 See other pics, this is an "in progress" pic.
Raised pivot (rearward travel path) swing arm with a rising rate linkage, floating rear brake, 4130 chromoly tubing, redirected chain to isolate suspension from pedaling, super strong and stiff and not terribly heavy (42lbs built as is). I have all of the geo specs but not with me. as you can see it has super short chain stays, the affective chainstay length is longer once you sit into the sag. The HT angle is about 65 degrees and bb ht is about .75 above axle line.

 You would seriously eat sh@t if that snapped!

 What a trick design, so elegantly executed. Frame weight?
