ZIPP SERVICE COURSE SL STEM

Since the introduction of our line of Service Course and Service Course SL components we’ve had amazing success with our pro level athletes in all disciplines. While the successes have been proving, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering, we are proud to introduce our completely redesigned line of Service Course and Service Course SL stems and seatposts.New 11/4 Service Course SL - OS (Oversized), shims to 1-1/8 with angle adjustability for ±4°, ± 6°, ±8°Leading stiffness-to-weight of 1.85g/NM per mmNew faceplate and body geometry for greater stiffness and easier installation
