What Makes the Zipp Service Course SL Stem Worth Upgrading To?

The Zipp Service Course SL Stem is machined from 7075 aluminum with a precision-engineered shape delivering a 1.85 grams per Newton meter stiffness-to-weight ratio, translating directly into no-flex sprints and sharp acceleration out of every corner. At +/-6°, it suits riders looking for a level cockpit with just enough angular adjustability to dial in their setup, and it is available in multiple lengths from 70mm to 110mm to match any fit requirement on road or gravel.

The four-bolt faceplate provides even, secure bar clamping with a clean aesthetic and a straightforward installation process. Designed for the standard 31.8mm oversized clamp diameter, the Service Course SL Stem pairs with virtually any modern handlebar on the market. It is the right call for racers and serious riders who want proven Zipp cockpit performance without moving into integrated or carbon stem territory, built to perform across an entire training and race season.

FAQ

What is the difference between the SL and standard Service Course stems?

The SL version is machined from premium 7075 aluminum and engineered to a specific stiffness target, making it stiffer and more precise than the standard Service Course stem while remaining in the aluminum category.

Is +/-6 degrees the right rise for me?

+/-6 is the most common stem rise for road and gravel setups, offering a nearly level bar position. If you need more stack height, consider the +/-17 version of this stem.

Does this stem fit carbon handlebars?

Yes. The four-bolt 31.8mm faceplate distributes clamping load evenly, making it safe and compatible with aluminum and carbon handlebars within the specified torque range.

Best For

Road racers and serious cyclists who want a proven, high-stiffness aluminum stem from Zipp with a +/-6 degree rise and multiple length options to match their fit.
