Thank you, this is a very, very helpful comparison, since I have actually tested the Roubaix (when bf was looking for a bike and since we're the same size and he's terribly indecisive, I was recruited to help test. It wasn't such a bad job actually ). The build we tested (carbon, Sram) was very stable and comfortable, but perhaps lacking in the "makes your heart beat faster" department (Cervelo R3 made our hearts beat faster...).

Btw I visited your dog's blog and I think he's gorgeous .
