Zipp SL Speed Stem

The unidirectional carbon layup is engineered to maximize stiffness while keeping weight to a minimum. This ensures that your steering inputs are transferred directly to the fork, providing a more responsive and precise handling feel compared to standard alloy stems.

Yes, the stem uses Torx T25 bolts for both the steerer and handlebar clamps. Using a T25 driver ensures you get accurate torque readings, which is critical for preventing damage to carbon components.

The Zipp SL Speed is a threadless stem designed for a 1 1/8-inch (28.6 mm) steerer tube and a standard 31.8 mm handlebar clamp diameter. Please verify these measurements on your current bike before purchasing to ensure compatibility.

No, this stem features a fixed 6-degree angle. It is designed to provide a consistent, high-performance geometry that cannot be altered, which helps save weight and increases structural rigidity.

This stem weighs 123 grams. The use of titanium hardware and a lightweight carbon body makes it an excellent choice for riders looking to shave grams off their cockpit without sacrificing stiffness.

The stack height is 41 mm. This measurement is important because it dictates how much steerer tube space the stem occupies; you need to ensure your fork's steerer tube has enough length to accommodate this height along with any headset spacers you plan to use.
