Carbon can be tuned in an incredible variety of ways, thanks to clever engineers tweaking resin and layup to achieve their benchmarks. And with the definition of a road bike rapidly changing, we wanted the Service Course SL seatpost to provide real comfort when venturing off-pavement.
The redesigned Service Course SL seatpost is a new carbon post from Zipp, specifically tuned to be more shock absorbing than the “comfort” seatposts on the market, while still passing our 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.
To ensure compatibility with most modern frame designs, the Service Course SL seatpost is available in a 400mm length, and three diameters: 25.4, 27.2, and 31.6mm. Weight is a svelte 240g for the 0mm setback and 249g for the 20mm setback.
