Zipp Service Course Road Stem packs in a wealth of style and strength without the hefty price tag.
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.
