This is clearly a road bike. A hubless wheel will add a tremendous amount of weight to the rim. Spokes significantly add to the radial strength of the wheel with very little weight. Without spokes, you will need to beef-up the rim weight a great deal to have an equivalent radial strength. You will then greatly increase the amount of rotational interia – your physics book hasn’t changed a bit in several hundred years with regards to angular acceleration. Racing bikes is a big business with a lot of money behind it. Why wouldn’t they invest in a better racing machine?

Yes we are art students, but we can convey our ideas on paper without autocad. We can do the research that is necessary of implementing next steps. We can design a product that not only works, but looks good and interacts with people in a positive way.

If we knew everything, we would be going to school for 8 years. We are students, we learn as we go, we aren't experts by any means. This design is beautiful and expresses itself as such. Criticisms are great, but don't pick apart our major because you are a pessimistic man who wants to keep product design strictly for engineers.

Interesting, but not something revolutionary. It’s actually 4 rollers, 3 lower and a moveable upper one to tension everything. The rim is actually 2 rims stacked and held together by carbon fiber. Which makes rom for the valve stem. It’s very noisy, and at the moment seems to have quite a lot of drag due to having 4 rollers and 8 bearings. It’s 650C and about the same weight as a regular fork and wheel. Slick looking, very trick in its day, but not a great wheel.

I’m not sure if it’s for sale or not but it’s on display on the sales floor along side with all their other bikes, I did not see a price tag though. If youre interested in more details on it, feel free to email me.

The story the guy told me (and I realize this is all heresay) is that the company spent $250K doing the R&D, set-up & fabrication and produced 3 of these wheels. The owner of the shop got one of them. They worked temendously well, and were noisy as hell, but they worked (by worked, implied that it was a vast improvement over conventional design). THEN, UCI decided that the wheels were ‘illegal’ for competition, and that was the end of the black hole. Application was for track riding only.
