Keep in my mind the roubaix frame I had was the low end carbon FACT 8R which I think had something to do with the way the bike felt. The BH Quartz's liveliness is similar to my Tarmac and has the same willingness to want to move forward. The ride on the BH is also WAY smoother than the roubaix, I'm curious if the carbon wheels/tires have something to do with it. The BH has a 1cm taller head tube, but the seat to handlebar height was the same as my Roubaix (3 inches). The one thing I liked about the roubaix was that it handled fast downhills with confidence.
