Stems

On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored color is available on the Zipp Service Course 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 reinforced our design decisions, 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 methods, we are proud to introduce our completely redesigned line of Service Course and Service Course SL stems. - Class-leading stiffness-to-weight ratio - More options for a better fit - New faceplate and geometry for greater stiffness and easier installation - Distinctive silver finish
