Is cosmic carbone wheels really a carbon wheel? how come the rim looks so much different from those rims like Zipp or AC? And if it is a carbon whee, how come it is so much heavier than other carbon wheels? Does anyone know?

They are essentially an aero carbon fairing over bonded to a low spoke count open pro rim.

As the other poster stated it's a carbon fairing bonded to an aluminum rim. It's not an OP however. The rim is propriety to the Cosmic Carbon and slightly narrower than OP. From the feel it also appears to carry a lot of weight in the rim itself. Mostly to allow for superior aerodynamics due to low spoke count and I've also heard some theories in regard to a "flywheel" effect to smooth your tempo. I've also seen some links (can't find them currently) to tests posted here a while back showing the Cosmic Carbone to be one of the most aero wheels you can get short from going full disc or 3 spoke.

I've ridden Carbones for 6 years, only wheels I rode for 2 years. They are fast but pretty heavy.
