Zipp Service Course SL Stem

The Service Course SL is engineered specifically for high-performance riding, utilizing 7075 aluminum and titanium hardware to achieve a superior stiffness-to-weight ratio. This reduces flex during hard efforts like sprinting or climbing, providing more precise handling compared to heavier, entry-level stems.

Yes, this stem features a 31.8 mm handlebar clamp diameter, which is the industry standard for modern road and gravel handlebars. As long as your current bars are 31.8 mm, they will fit perfectly.

No, the angle is fixed at 6 degrees. You can flip the stem to run it in either a positive or negative orientation to fine-tune your cockpit height, but the angle itself cannot be adjusted.

This stem weighs 125 grams. While saving a few grams here won't drastically change your bike's overall weight, the real benefit is the increased stiffness, which improves power transfer and steering responsiveness.

While it is designed primarily for road and gravel use, it is compatible with any bike using a standard 1-1/8 inch (28.6 mm) steerer tube. However, keep in mind it is optimized for road-style riding rather than aggressive mountain biking.

Yes, the four-bolt removable faceplate allows you to install or swap handlebars without needing to remove your shifters, brake levers, or bar tape. It makes cockpit adjustments significantly faster and more convenient.
