I'm curious as to which frame is better, and why. I can't seem to find any info on non-Evo frames from Cannondale, and from what I can tell, the FC seems like a great frame for the money; but is it head-and-shoulders above the entry-level offering from Cannondale?

Supersix frame is 900g and FC is 938g if the internet doesn't deceive me. Geometry is a touch different. Prices are within a few hundred of each other one way or the other depending on where you look.

I'm guessing by "entry-level" you mean entry-level carbon frame from Cannondale. Only real difference between the normal Supersix and the EVO is the "high-modulus" carbon which shaves some more weight to the tune of ~200g.

Where did you find this? And yes, by "entry-level" I mean the non-evo Supersix.

Also, why would team Exergy, a professional team, use the Felt FC frameset and not the F1?

Also, is all high modulus carbon the same? Felt says they use hi-mod on the FC frame, whereas the normal supersix is just your run-of-the-mill carbon?

1. Sorry, found that on an old review from a 2010 Supersix where they got the real naked weight of the frame. I'm guessing it's somewhere close to that for 2012 . . . b/t the Cadd10 at 1050g claimed and the EVO at ~700g.

2. As far as why Exergy would use the FC frameset, I have no idea. Guesses: (a) they like it better or (b) they are getting paid to. I realize the F1 is lighter, but lighter isn't necessarily "better." Getting back to your original question, "better" is pretty vague. As in, lighter, stiffer, value for the money, handling characteristics, aerodynamics, aesthetics, something else?

3. No. High modulus refers to the tensile modulus (stress over strain aka deformation measured in millions of pounds / square inch). For advertising purposes, high-modulus is considered a legally informal term and could describe any carbon fiber composite with a modulus of 33-55+ MSI. To put it simply, the higher the modulus, the stiffer the CF (and the more brittle). To make an equally stiff carbon fiber frame of lower modulus, you need more layers, adding weight. The term "high-modulus" also provides no indication of what actually goes into the composite and in what ratios - carbon fiber, epoxy, nylon, aluminum, kevlar, etc, or any of the other bazillion variables between different types of CF's. You would have to call the company and ask, but it's probably a proprietary formula.

Thanks for the info on modulus. I know the geometry is slightly different, but how do those numbers translate out on the road? Is the Felt slightly more relaxed? I know "better" is vague, I guess I really just wanted people's opinion on the frames; preferably people who ride them.

Test ride both frames and go with the one that feels best to you.

Well, I have a 2012 supersix 5 right now, but the bike feels slightly too big (58 cm). My last bike was a 57 cm BMC that fit perfectly. The problem with the Felt is that no shops around me have them built up since it's only sold as a frame set.
