team frame sponsors change, and riders are obligated to use new equipment. fortunately, bike are not all that different. generally, available frame sizes match up pretty well. the only things that needs to be done is to sort out what stem will give the same stack and reach as the old setup - with the variety of options from stem sponsors, there's sometimes more than one spacer/stem setup that gets equally close to the previous position, when the bar position is sufficiently high above the head tube. so, you get to choose which you think looks better (flat with spacers, up with fewer spacers)
