Zipp lost the patent on the rim profile they had been using for the last x years, but have now moved onto firecrest, which, if their marketing gubbins is to be believed (is it ever?), is vastly superior. so they remain one step ahead. I'm now sounding like a Zipp apologist, which I'm not, but I feel one should appreciate that not all deep section wheels are created equal.
