I checked them out and I am dubious. I'm a big guy, and I'll assume one of the bikes with 64cm frames would work for me. I know I would have to upgrade the wheels soon. Don't know if you can have them put on different handle bars, seat posts, long cranks, etc before shipping. Also, the "ultegra" bikes I looked at were not 100% ultegra. I don't know if the substitutions are better or worse. But that would be another set of parts one would possibly have to upgrade/repair soon. And I would still have to take it somewhere to get it adjusted for my fit.
