Zipp Service Course SL Stem

This stem is built for road cyclists who want a balance of stiffness and low weight. Its 7075 aluminum construction makes it rigid enough for sprinting and hard accelerations, while remaining light enough for climbing-focused builds.

The Zipp Service Course SL is designed for standard 31.8mm diameter handlebars, which covers the vast majority of modern road bike cockpits. Please double-check your handlebar diameter before purchasing to ensure compatibility.

A 6-degree angle is a standard road geometry that allows you to run the stem in either a positive or negative orientation. This gives you the flexibility to either raise your handlebar height for a more upright position or lower it for a more aggressive, aerodynamic stance.

The stem features a 'Nano Blast' finish, which is specifically engineered to be more durable and resistant to the wear and tear of daily riding than standard painted finishes. It maintains a clean, professional look even after repeated adjustments.

The stem uses T25 Torx bolts for the faceplate and steerer clamp. You will need a T25 Torx wrench to install it, which is a standard tool for many modern cycling components and less prone to stripping than traditional hex bolts.
