I have about 400 miles on my Emonda SL6, and I really think Trek is missing the mark with how they are marketing the bike. Their ads and webpages for it go on and on about how light it is, but what is really the story is how it rides. It is stiff and light for sure, but they didn't sacrifice ride to get there. I rode a Tarmac and a Madone on the same day I test rode the Emonda, and the Emonda felt stiffer and more responsive than the Madone and smoother than the Tarmac. I did not ever get the chance to ride a Roubaix, because I had convinced myself that the "endurance" bikes were too mushy after riding a Domane. I only read after I bought that Specialized had stiffened up the SL4. Sounds like it would have been a tough choice between the two if I had test ridden the Roubaix.
