The Service Course® stem delivers all you look for in a high-performance stem -- strength, stiffness, reliability, a precise fit and great visual look. The redesigned Service Course stem offers a new faceplate and body design for greater stiffness and easier installation at a price that meets any rider’s budget. On today’s road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored component color is available on the Zipp Service Course stem.

The Service Course Stem’s new shape and 3D-forged construction results in an improved stiffness-to-weight-ratio of 1.75g/nm. The stem design, along with its clean new graphics, also complement the aesthetics of modern frames. Made from 6061 aluminum, the stem resists flexing during sprints and accelerations.
