When you need a well-built, totally reliable seatpost at a great price the Zipp Service Course is a top choice. It is light weight and strong for security and designed to offer a precise fit at an affordable price. It also provides easy tool access to the downward facing bolts for easy setup and micro adjustments after it’s mounted. Better bike fit can facilitate better performance to make you faster. An out-of-position saddle means wasted energy with every pedal stroke.

The one-piece shaft design and top clamp plate are 3D-forged from 6061 aluminum for an optimal combination of strength and weight. The secure, low-profile clamp allows the saddle to slide farther back along the rails, and with 0 and 20mm setback options, it’s possible for nearly any rider to achieve the perfect fit. Both 27.2mm and 31.6 mm diameters are available in both Zero and 20mm Offset, and all models are 350mm in length
