Zipp Service Course SL Stem

The 7075 aluminum alloy is a high-strength material that allows Zipp to create a stem that is exceptionally stiff while remaining lightweight. This ensures that your power transfer remains efficient during sprints and hard efforts without adding unnecessary weight to your bike.

This stem is designed for a standard 31.8 mm handlebar clamp diameter and a 28.6 mm (1 1/8 inch) steerer tube. Please verify these measurements on your current setup before purchasing to ensure compatibility.

Zipp uses TORX heads because they are less prone to stripping than standard hex bolts. This allows for more precise torque application and makes it easier to achieve the correct clamping force without damaging the bolts.

A 17-degree angle is considered a 'flat' stem, which typically results in a more aggressive, aerodynamic riding position compared to the more common 6-degree stems. It is a great choice if you are looking to lower your handlebar height for a racier fit.

Yes, the faceplate is fully removable, which makes swapping handlebars or performing maintenance straightforward. The machined design also helps reduce weight without compromising the security of the clamp.
