SJX426, Thanks for reminding me, I forgot to include the frame size for the two C'Dales... 58 cm.

noglider, I guess I'm in the minority WRT detecting a small weight difference... I can feel the difference between a road frame and a touring frame, if I ride them back-to-back. I wonder if I'm insensitive to my two primary bike's weight difference because I weigh ~190 lbs.? Bike to bike difference is 16.492% while adding my weight to the equation it becomes a 1.506% difference. A 130 lb. rider would have an overall difference of 6.15% (My math is always suspect!)
