Zipp Service Course 6°

Pro-Level Performance & Precision.

The Zipp Service Course Stem is engineered to meet the demands of the pro peloton, offering a rock-solid connection between your handlebars and your fork. Forged from 6061 aluminum, it strikes the perfect balance between high stiffness. For explosive out-of-the-saddle sprints, and light weight. Whether you're building up a new road race machine or looking to dial in your fit on a gravel rig, the Service Course stem delivers the legendary "Zipp" quality in a rugged, dependable package.

Why the Service Course Stem is a Shop Favorite:

• Forged 6061 Strength: Forged from high-grade aluminum for maximum durability and strength-to-weight ratio. This stem is designed to handle the high torque of powerful sprinters and the chatter of rough gravel roads.

• Redesigned Faceplate & Body: The updated body shape and faceplate design increase the clamping surface area, ensuring your handlebars stay secure and silent, even under heavy load.

• Precision Fit: Available in a wide variety of lengths, allowing you to fine-tune your reach and drop for the perfect aerodynamic or endurance-focused position.

• Sleek Aesthetics: The bead-blasted finish and updated Zipp graphics give this stem a premium, "stealth" look that complements any modern frame, from classic round-tube steel to aero carbon.

• Ease of Installation: Uses stainless steel Torx® T25 bolts throughout. This ensures more reliable torque readings and prevents the stripping often seen with standard hex bolts.
