Just went out at lunch and test rode a Cannondale CAAD8 and Felt F65. Both are Ultegra with compact cranks. I liked the Felt a little better. It was not as harsh as the Cannondale. I will go back though and ride a Cannondale Synapse with carbon stays to see if it's better. I might even ride a full carbon, just for kicks.
Oh No , am I turning into a Bombadil. Test riding road bikes at lunch searching for that perfect fit until hell freezes over.
