I have the 928 C2C Ultegra and I love it to death. Comfy and smooth. Fits my riding style to a T. I ride long straight routes for miles on end. It absorbs bumps very well, but I run 700x25 clinchers at 90psi, so that may have something to do with comfort too.

As for the made in Taiwan Bianchi's. Apparently, American sold Bianchis are unique to the American market, with the exception of the "RC" models and maybe the cyclocross concept, but almost all the other models are designed for Americans by Americans (by Bianchi North America) and produced in Taiwan. No differently, there are models in Japan designed uniquely for the Japanese market. Bianchi has a very sophisticated marketing arm that caters to individual countries. Just as there are several Euro only models that Americans have no access to.
