Zipp Service Course Seatpost;

Zipp's innovative, low-profile clamp provides a wide range of adjustments to both angle and for-and-aft position. This adjustment range makes the Service Course Seatpost suitable to a wider range of riders and lets you dial your fit and feel. That isn't the only feature that sets the Service Course Seatpost apart, however. Zipp engineers paid special attention to the length of the clamp assembly. On the lower portion, it's designed to be a bit longer than what you might see on other seatposts. Essentially, this is to support the saddle rails if you favor to ride at the rearward position. And in this day and age of super-light rails, we view any extra insurance against damage as a welcomed friend. For this iteration of the Service Course, the seatpost forgoes carbon fiber in favor of a one-piece, 3D forged design. If you pay close attention to the Grand Tours, you'll notice that this is a reoccurring trend in the peloton. The reason is simple. For the cost of a few grams, the seatpost becomes stiffer, stronger, and more comfortable that its carbon fiber counterparts. In fact, we find that road vibration is better dispersed, while power is better conserved during seated exertions.
