The all-new 2010 Cannondale SuperSix dropped last August and I have spent approximately 2,000 miles on the saddle of one of the first examples to hit stores. If you want the short version, it's a phenomenal bike and I highly recommend it. If you want the long version, read on.
The SuperSix is one of the latest entries into the superlight, vertically stiff/laterally compliant superbike fray. My size 52cm bike built up with race wheels, computer, pedals, and bottle cages to 14.5 pounds for a complete ready to race bike (see complete specs below). Although I received the SuperSix Hi-Mod 1 which comes spec'd with Shimano Dura-Ace, I stripped the Dura-Ace shifters and derailleurs and replaced them with a SRAM Red/Force mix in order to lower weight and save money. Plus, I simply prefer SRAM.
Highlights on the build include a frame which features a tapered head tube, massive "Beat Box" bottom bracket (BB30, of course), carbon cable stops that are molded into the frame and even full carbon dropouts and front and rear (although the rears feature aluminum clamping surfaces to prevent damage) to save weight. The sub-600 gram Cannondale Hollowtech BB30 crank comes assembled with standard chainrings but inlcudes all the necessary tools and parts (including an extra set of FSA chainrings and bolts!) to convert it to compact.
The finishing kit on the SuperSix 1 is pro-tour ready with a complete FSA K-Force cockpit and seatpost, Fizik Arione CX saddle and Mavic Ksyrium SL Premium wheels. Sure, most folks will swap out the Ksyriums on race day for something deeper in carbon, but it wasn't too long ago that Ksyriums were being ridden up mountain passes in the grand tours. I'd race them with no hesitation and they make a great bullet-proof yet lightweight "everyday" wheel.
The first time I hopped off the 2009 SuperSix I said "that's a perfect crit bike." The 2010 model retains the 2009's crisp, precise handling and instant power transmission whilst cutting frame weight - the black/white version of the SuperSix Hi-Mod frame weighs in at 837 grams for a size 52cm. In spite of the HUGE frame tubing the SuperSix evinces a surprising level of comfort. I did notice a slight increase in road buzz compared to say, the Orbea Orca, but I feel that the SuperSix is at least if not more comfortable than similar superbikes such as the Specialized Tarmac and Trek Madone and definitely more comfortable than rigs like the Cervelo Soloist.
The massive tubes and asymmetric chainstays combine with the aluminum BB30 crank to create a pedaling platform that gives no sensation of power loss. Stomp on the pedals and the SuperSix goes NOW. If you get dropped from your local Tuesday Night Worlds on the SuperSix you certainly won't be able to blame it on the bike. Another nice frame feature that smaller riders such as me might appreciate is the very slightly sloping top tube which allows you to run two full-size water bottles. I've often been able to carry only a small bottle on the seat-tube position due to the slope of other frames.
An interesting note on the Hollowgram SL crank - unlike most crank manufacturers, Cannondale fashions their super light crank from aluminum instead of carbon. Each crankarm is actually two precisely machined and press-fit pieces that leave a hollow void in the middle of the crankarm. All SuperSix Hi-Mod 1s also ship with the extra interchangeable spider in 110 bolt circle diameter so you can choose compact gearing, standard gearing, or even swap back and forth. Cannondale also makes the same basic design in a mountain bike crank.
Overall impressions? The SuperSix provides excellent handling, a solid, responsive pedaling platform and a ride that won't beat you up as much as many other "stiff" bikes at the end of the day. I have to say that even after 2,000 miles the prevailing feeling I always get from the SuperSix is one of rock-solid stability. It never fails to go exactly where I point it and it always feels as though every bit of power I make goes straight into the rear wheel. My complaints about the Supersix? The headtube may be a little short for some, but those looking for a more comfortable ride should probably be looking at bikes in another segment anyway. Other than that, my only complaint is that I couldn't get one in black.
Another nice thing about the SuperSix lineup - if you forgo the flyweight components and "Hi-Mod" carbon frame (I suppose you get "Regular-Mod" instead?), you can get the same great performance and handling for as little as $3,750 MSRP. Or, if you're an extremist and regional Category 4 champion hopeful, you can get it decked out complete with Zero-G brakes, DT carbon wheels and SRM for a mere $13,300. Each of the build/pricing levels on the SuperSix is well thought out.
