Zipp Service Course SL Carbon Seatpost
The Zipp Service Course SL carbon seatpost is designed with a focus on fit, performance, and ride comfort. Its lightweight unidirectional carbon tube is specifically tuned to be more shock absorbing than the “comfort” seatposts on the market while still passing Zipp’s strict internal MTB strength test. Flex engineered into the carbon tube helps keep the rider comfortable over any terrain. A properly positioned saddle can contribute to better performance, while the secure two-bolt clamp allows easy micro-adjustments to saddle position. The seatpost head has also been redesigned for maximum bolt head accessibility, making saddle adjustments easier.
The Service Course SL seatpost is available with 0mm and 20mm setback options, allowing flexibility when positioning the saddle. Its clamp works with all saddle rail types, and the lightweight clamping system complements the seatpost's carbon construction. This version features a 20mm offset/setback, updated distinctive Zipp cosmetics, and a 400mm length. It is available in three diameters—25.4mm, 27.2mm, and 31.6mm—and includes a lifetime warranty.
