Zipp: Zipp first developed the Service Course SL stem for the fit and performance needs of pros. That goal of being pro grade has proven out over the past several seasons as the stem became a mainstay in the pro peloton and cyclocross circuit being ridden to victory in Paris-Roubaix and the Vuelta a Espana. Now, we take that pro-proven legacy and build on it with the redesigned Service Course SL stem.The Service Course SL Stem, crafted from 7075 aluminum, features a redesigned shape that's strong and lightweight, resulting in a best-in-class 1.85 grams per newton meter of stiffness. That results in no-flex sprints and accelerations. To meet every rider's fit needs, the stem is available in 6 and 17 angles and seven lengths from 70 to 130mm as well as a 140mm length for the 6 stem only.

Zipp: 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.
