Zipp SL Sprint Stem

The unidirectional carbon layup is engineered specifically for stiffness-to-weight efficiency. It provides the rigidity needed for aggressive, high-wattage sprinting while keeping the overall weight down to 165g, making it suitable for both flat-out speed and climbing.

Yes, because the stem uses precision TORX head bolts, you should use a torque wrench with a TORX bit to ensure you hit the exact manufacturer specifications. This prevents over-tightening, which is critical when working with carbon components.

The Zipp SL Sprint is designed for a 31.8mm handlebar clamp diameter, which is the industry standard for modern road bikes. As long as your current bars match this diameter, it will be compatible.

The integrated cap is designed to smooth airflow over the stem body, reducing drag. While it creates a cleaner aesthetic and better aero profile, it functions just like a standard cap, so it won't complicate your routine maintenance or cockpit adjustments.

This stem has a stack height of 41mm. This measurement is important because it dictates how much of your steerer tube the stem clamps onto; you need to ensure you have enough steerer tube length available to accommodate this height for a safe installation.

While it is built for the rigors of professional road racing and sprinting, its stiffness makes it a great choice for any rider looking to improve power transfer. However, keep in mind it is optimized for a 12-degree angle, which provides a fairly aggressive, performance-oriented position.
