With the integrated seat mast, the new Madone may raise some questions about fitting. The new Madone’s seat mast is different from most, because it can’t be cut. Instead, all height adjustment comes from sliding the seat cap up or down on the mast, and by choosing a standard or long seat cap.
Above, the top photo shows a few of the new Madones ridden in the Trek 100 this past weekend. The second one is a close up of the seat installed on the seat cap on the frame. The bottom photo shows the frame’s seat mast with the seat cap removed. You can see the height graduation marks. The top one must be covered by the seat cap; that’s the maximum height. Incidentally, the top of the frame’s seat mast is completely closed. Don’t cut that off; it not only keeps a lot of water out of the frame, it also contributes to the strength of the mast.
On the left is the long seat cap (optional), and on the right is the standard seat cap (included).
With that understanding of the seat mast and seat cap system, here’s a table showing the range of saddle heights you can achieve with the two seat cap lengths. Click on the thumbnail image to get the full size version.
