Yeah I posted quite a bit about it in another thread. I'm 5'10" and I tried a 56 cm Roubaix and a 54 cm Roubaix Sport. The 54 put me in a more upright postion which I liked and not that much more aggressive stance meaning the seat adjustment was not that much more higher than the handlebars for the 54 over the 56. I definitely like being more upright. But everyone I talk with seems to think at my height I should go with a 56 cm. I spoke with a professional bike fitter at a different shop and he says no way he would fit me on a 54. But as he mentioned there also is a lot of variances between the different bikes.
If choosing the 56cm Roubaix I'm saving $600 but giving up better wheels and going down to Tiagra vs 105.

I would not really be happy with a 54, regardless of what is done with stem or seat adjustments. Might work to get me from A to B, but it wouldn't be nearly as good as the fit with the 56 frame.
