Zipp Service Course 31.8 Vorbau

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 now offers a new faceplate and body design for greater stiffness and easier installation at a price that meets any rider’s budget.

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.

The Service Course Stem also is available with a +/-6° in eight lengths from 60 to 130 mm.

For added fit options and to help riders achieve an efficient and maintainable position, we’ve added a new ±25° Service Course Stem available in 75, 90, 105 or 120mm lengths.
