The Zipp Service Course seat post is lightweight and stable in terms of safety and is designed to provide a precise seating position at a reasonable price. The downward-facing screw is easily accessible, allowing for simple adjustments and fine-tuning after installation. A better seating position means better performance, making you faster. A saddle that is not positioned correctly leads to wasted energy with every pedal stroke. The secure, flat clamp allows the saddle to slide further back on the rails, and with offset options of 0 mm and 20 mm, it is possible for nearly every rider to find the perfect seating position. The shaft and head are not pressed but are 3D forged from 6061 aluminum to achieve high strength, low weight, and efficient use of every gram. The Service Course seat post has a length of 350 mm and is available in diameters of 27.2 or 31.6 mm. It fits all common saddle rails.
