So I rode a 2008 Specialized Roubiax Elite Compact today and loved the feel of a full carbon bike and then I went and rode the 2009 Carbon Synapse 5. I have to say the full carbon synapse took all the road buzz away compared to the aluminum one I test rode last week. I love the fit of both the Roubiax and the Synapse 5. But I cant make up my mind. I guess I'll let the best price decide at this point. Unless anyone has any more input.
