I see. Not the Pro Carbon. Similar geometry in x-large though. A 20.5 cm head tube on a large Victeur is highly unlikely. That would have put it in Specialized Roubaix territory. Your new bike likely just moves the handlebar 1-2 cm out and 1-2 cm up. Presumably, you upsized because the large (57-58 cm) was just too small for your 6'3"? Did you mention your leg length?
