I looked at the Roubaix today. The base Roubaix definitely looks like a step up from a base Pilot, but it's also about $300 more and I'm already at the top of what I'm willing to pay with the base Pilot. My sales guy is checking to see if they have any of last years models at their other stores, but he said they were pretty popular last year so he wasn't optimistic about having any. In size 52, the geometries of both are very close with the only significant difference being the almost 1 degree greater seat angle on the Roubaix.
