The Zipp Service Course SL Seatpost is specifically tuned to be more shock-absorbing than the "comfort" seatposts on the market, while still passing the brand's strict internal MTB strength test.
Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain.
Better fit means better performance, and if your saddle is out of position, you'll waste energy with every pedal stroke.
The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt head accessibility.
With 0mm and 20mm setback options, it's possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types.
