This design is silly.

Because it makes the BB stiffer, and Rotor, SRAM and FSA are making specific cranks for it - which are simply BB30 cranks with longer spindles and a shallower NDS arm.
Campy is making a specific adapter for it, and Shimano doesn't support either BB30, BB86 or BBright, so that makes BBright no less stupid than the other two.
I'm not much of a Cervelo fan, but the design seems to work and hasn't been plagued with the problems of BB90, and gives more heel clearance than BB86, so I'm not sure why it is any sillier than tapered steerer tubes or 31.8 bars.
