Overview

Is the Zipp Service Course Stem +/-6 the Right Pick?

The Zipp Service Course Stem in +/-6° delivers the strength, stiffness, and visual quality that riders expect from a Zipp cockpit component at a price accessible to any build budget. Its redesigned faceplate and body construction improve stiffness over previous versions and make bar installation cleaner and faster, with a four-bolt faceplate that uses Torx T25 bolt heads. Zipp makes the Service Course Stem in +/-6° and +/-25° angles, and the +/-6° version gives you a near-level cockpit.

Available in 60mm through 130mm lengths to cover a wide range of rider geometries and frame sizes, this stem pairs with any modern 31.8mm oversized handlebar and installs without fuss. Whether you are speccing a race build, upgrading an OEM stem, or fine-tuning your position with a shorter or longer reach, the Service Course Stem gives you Zipp quality in the cockpit without needing to step up to the SL version to get there.
