Yeah that's supposed to be the "six". There are pictures of that bike floating around on roadbikereview in the cannondale section iirc.

Next in the Elite category is the all new Six Carbon. Learning from its big brother the Six Carbon’s monocoque front triangle features a trapezoidal head tube that tapers from 46mm-52mm housing a full carbon fork with alloy drop outs. The top tube, while being tuned for lateral stiffness with a 44mm horizontal cross section also adds style points.
Known for quick acceleration inherent in oversized down tubes,
the Six Carbon sports a large 57mm down tube at the BB30 bottom bracket. Rounding out the full carbon frame are 15mm independent left and right hourglass seat stays aiding in the comfort department while optimized chain stays handle axle loads putting power to the ground. Each of the eight frame sizes has a size specific rear carbon drop out eliminating heavy unwanted rivets. You’ll find the line of Six Carbon models spec’d with Shimano Dura-Ace at US$4,000, Shimano Ultegra SL at US$3,000, Shimano 105 at US$2,100, and a mix of Shimano 105/Tiagra at US$1,900.
