Zipp: The Service Course 80 provides comfortable and efficient positions on the tops or hoods or that aero and efficient position in the drops. The bar allows a neutral wrist position on the drops and a flat brake hood transition for the athlete even while riding with a more upright position. This minimizes the need for up-rotated bars. The bar s drops are angled outward by 4 degrees to reduce wrist strain.The Service Course-80 is named after its 80mm reach (horizontal distance from the bar s stem clamp area to center of the brake perch). That brings the hoods and control levers back where you want them, while keeping the drops close and usable "e; all without requiring a shorter stem. The ergonomic 125mm drop (vertical distance from bar s stem clamp area to bottom of drops) places the angled drop position where you can easily reach it while maintaining a neutral wrist angle. These are the same drop dimensions as the Service Course SL-80.All of that works together to provide comfort and aerodynamic efficiency for when the hammer is down.The Service Course 80 is clip compatible and is crafted from 6061 aluminum.
