I knew I wanted a more aggressive frame when we kept swapping out spacers and flipping my stem to get me lower...and I still felt cramped and too upright. We had considered trying a longer stem, at that point, but I already felt like the steering on my Synapse was sorta numb, so I was afraid that a longer stem would only increase the lack of responsiveness.

Plus I found the aluminum on the Synapse to be very buzzy on our rough roads. What is interesting is that I have talked to people who have ridden the alum CAADs and the Synapse and also found the Synapse to be a rougher ride. This kind of surprises me, since I would have thought that more relaxed and flexible geometry would have dampened vibration more, not less.

I must say that I am very fond of my carbon SuperSix, though. It really smoothes out some roads that I had avoided after they were freshly chip-sealed last Summer. For me it's just as comfortable on long rides as it is on shorter, faster ones. I think a lot of this comfort depends upon a person's flexibility and physique, though. I have a long torso relative to my legs, so I like the longer reach. With my Synapse I was on the right size for my leg length, but had a really difficult time in the drops, since the cockpit was shorter than on the SuperSix.
