The Cannondale option definitely looks good, but it's a bit too rich for my blood. I've seen those OEM Rotors, but if I'd go down that path I'd get Easton EA90s instead.
I also fancy the EA90s from an aesthetical perspective, but the chainring combos are very expensive and you get the same problem with the Middleburns that the axle is bonded to the crank arm and iirc they're quite short. So no good with a bsa30 setup.
