Not sure about that. I've only had the Roubaix a few days. The Allez is more compact, but heavier (aluminum vs carbon fiber), and I'm more used to it (triple vs double). Still getting the feel of the Roubaix (and trying to figure out this complicated Cateye computer that only works when it wants to ). In the long run the Roubaix is more comfortable and will be quicker.
