New Carbon bike--isotruss

[Thunderchild]

Another High-carb bike may enter the market.  Check out the Isobike at the links below.  I may even get a chance to test one out.  A bit of information that I learned from one of the engineers/designers follows:  Number 4 has been tested at the Specialized bike frame testing facility, and it passed.  The structure offers incredible aerodynamics (more important to roadbikes, but interesting) over a standard tube.  Mountain bike tubes will be wrapped to keep debris an dirt out of the center.  I can see that tumble weed or stick wedging in there.  #4 was constructed with a titanium lug set.  It is very rigid and does not flex eventhough it looks like it does.  I also asked one of the designers about noise.  He said there is none, but commented that it would be nice to engineer a unique whistle or sound that high speeds would generate.
