Zipp Service Course SL Stem

This stem is constructed from high-grade 7075 aluminum. This material choice provides a balance of low weight and high stiffness, making it a reliable option for road cycling.

The Zipp Service Course SL is designed for handlebars with a 31.8mm clamp diameter, which is the industry standard for most modern road bikes. It is not compatible with older 25.4mm or 26.0mm bars.

Yes, the stem is compatible with integrated computer mounts. This allows for a cleaner cockpit setup by attaching your cycling computer directly to the faceplate rather than using a separate handlebar clamp.

The 6-degree option is typically used for a more standard, slightly upright riding position, while the 17-degree option allows for a more aggressive, lower position. Choosing between them depends on your current bike fit and whether you need to raise or lower your handlebar height.

While designed primarily for road cycling, the 7075 aluminum construction is robust enough to handle the rigors of gravel and cyclocross. Its stiffness ensures efficient power transfer during the intense accelerations often required in those disciplines.

The stem uses T25 Torx bolts for the faceplate and steerer clamp. You will need a T25 Torx wrench to install it, and we highly recommend using a torque wrench to ensure you tighten the bolts to the manufacturer's specifications.
