Zipp Service Course Stem

Your stem has to resist flexing during sprints and accelerations, clamp securely to the fork and handlebar, and support your weight over significant impacts. It’s a difficult job, but the new Service Course stem is still able to combine strength, stiffness, and reliability at a weight of 130 grams (100mm).

High-strength 3D-forged construction and 7075 aluminium deliver an exceptional strength-to-weight ratio while allowing for smooth lines to complement the aesthetics of modern frames. During production, we take extra steps to ensure precise length and alignment across a range of fourteen sizes to meet any rider’s fitting needs.
