This is exactly the point. Not everyone can afford Zipps, but they would still like a deep section rim that is reasonably light, so that the aerodynamic benefits aren't completely counter-acted by the increased weight.

Regarding the freestyling comment, the owner has come out and said these rims are not meant to be "bomb-proof" like other deep section rims on the market. To get the weight down you need to remove material, and that's how they did it, plain and simple.

Lastly, the closest you're gonna get to a picture of someone racing or training on these things is on weight weenies. These rims have been on the market for what, a few months? What are you expecting?
