Agreed that we should compare the CAAD and the Synapse Alloy with respect to the frames only - not the bias of the attached components.
Comparing a size 56 CAAD and Synapse Alloy, both having a 56 cm top tube and 73.5 deg seat tube angles, here's a summary:
- the head tube on the CAAD is shorter and steeper than on the Synapse
- wheelbase on the CAAD is shorter than the Synapse's
- chainstay on the CAAD is shorter than the Synapse's
Obviously the Synapse frame is "larger", and as the former poster pointed out the Synapse has thicker tubing, making it heavier than the CAAD. Furthermore the CAAD is manufactured with a newer process making the tubing even thinner without sacrificing strength (according to Cannondale), making it even lighter.
A "smaller" frame on the CAAD makes it stiffer, and the more compact geometry makes it more responsive in terms of power transfer and steering.
The "larger" geometry on the Synapse makes for a more relaxed (upright) position than on the "smaller" CAAD.
Not sure what you mean about the Synapse frame feeling sturdier. I specifically bought the Caad9 over an alloy Synapse because the Synapse felt more flexy. Not as noticeable on the carbon model I eventually bought.

Looking at a used 2012 CAAD 10 5 in black. Has anybody seen the black with RED handle bar tape new? All the pics I see show black tape. For some reason the red has me weirded out.....
