Just got back from the maiden voyage. What a GREAT ride.

VERY comfortable and the shifting is just like the shop mechanic said -- smooth as silk.

Even better than the "old" Ultegra on my Litespeed.
I had Schwalbe something tires on the CAAD 10 and the ride was ok but these tires are Schwalbe Legano. Very nice.
I'm happy, happy, happy.
