I think they're both great-looking bikes. I would, like [MENTION=159681]Bianchigirll[/MENTION] suggested, get the Bob Jackson and sell the components and outfit it with older parts. I love the color scheme and Davis sloping fork crown. While the Serotta is also an attractive bike I don't like the old carbon fork (possibly a Look fork). I would guess tire clearance will be ever so slightly better on the Jackson as well.
