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.
