Zipp Service Course SL Seatpost 20mm Setback 27.2mm Diameter 400mm Length Matte BLK C2

Designed to minimize vibrations and maximize power on every pedal stroke, this carbon seatpost cushions the ride without sacrificing efficiency. The unidirectional carbon fiber and the aluminum head with a lightweight clamping system keep saddle position secure, so you can focus on the miles ahead rather than micro-adjustments. With 0mm and 20mm setback options, you can dial in a perfect fit for your anatomy and riding style.

Who is this for?

Performance-minded road and gravel riders who demand a precise saddle fit, reliable clamp security, and real vibration reduction will benefit most. This post suits riders upgrading from alloy or lower-grade carbon posts and those seeking a lighter, more comfortable ride without compromising saddle alignment.

Each item is professionally packed and shipped next day. Select in-store pick-up at checkout and visit us if you are local!
