The Zipp Service Course stem delivers all you look for in a stem—strength, stiffness, reliability, a precise fit, and distinctive look. The Service Course stem offers a faceplate and body design for greater stiffness and easier installation. It’s high performance and high value. The Service Course stem’s shape and 3D-forged construction results in an improved stiffness-to-weight-ratio. Made from 6061 aluminum, the stem resists flexing during sprints and accelerations.

This stem provides a higher angle ( 11 degrees) than our stock WABI stem if you want to raise the bars while also accommodating 31.8mm handlebars. These pair well with the Zipp alloy and carbons bars we offer.
