Service Course Seatpost - No Packaging

What Our Gearhead® Experts Are Saying:

"This seatpost does exactly what it should—locks the saddle in place and doesn't budge. I’ve used both the 0mm and 20mm offset versions depending on my bike’s geometry. The low-profile cradle is great for fine-tuning and keeps the ride setup sleek and simple."

With its clean design and precise adjustability, the Zipp Service Course Seatpost brings a balance of performance and value to road and gravel setups alike. Whether you're chasing KOMs or logging long training miles, the AL-7050 forged construction offers a strength-to-weight ratio that stands up to punishment without weighing you down. The bead-blast finish adds a refined touch while providing low-profile traction to reduce slip during installation.

The two-bolt, micro-adjust clamp is a standout feature, offering independent tilt and fore-aft control so you can fine-tune your saddle position for endurance comfort or aggressive racing posture. Riders will appreciate the ease of setup and confidence that their seat position stays secure even under heavy torque or on washboard gravel.

With 0mm and 20mm setback options, this post easily adapts to different frame geometries and rider preferences, making it a go-to choice for those building out custom rigs or tweaking fit for peak efficiency. Its 31.6mm diameter and 350mm length hit the sweet spot for most modern road and gravel frames, ensuring broad compatibility.
