Zipp Service Course SL Seatpost 31.6mm 400mm Offset: 20mm Black
On demanding trails, ride comfort and precise saddle positioning make all the difference. This carbon seatpost blends a forgiving flex with a secure two-bolt clamp, smoothing out chatter while keeping your saddle perfectly aligned. A redesigned head improves bolt accessibility for quick setup, so you stay focused on line choice and ride quality rather than fiddling with hardware.
Who is this for?
Designed for riders who demand performance with real-world comfort—endurance racers, mountain bikers, and everyday enthusiasts who want a lightweight, strong post that adapts to rough terrain and varied saddle rails.
