Thank you for your quick reply! I'm leaning towards the CAAD in size 60 or 63. I'm 6'5" and my inseam is right around 36". It seems like either frame would fit ok, so I'm thinking the 60 with a 3cm shorter head tube might be better for a more aggressive posture so that my elbows aren't placed too high. Also, I've been shocked at how expensive some of these wheels are! The 105 seemed to shift just fine, and as I'm 195lbs, I'm not worried about shaving ounces off the bike with a higher groupset. I've heard that wheels are your best first upgrade, but are aerowheels like a pair of zipp404's really worth doubling the cost of the bike in a race?
