Zipp Service Course SL Carbon Seatpost
The Zipp Service Course SL carbon seatpost is designed around 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. The engineered flex in the carbon tube helps keep the rider comfortable over any terrain. Proper saddle positioning is important for achieving a suitable fit, and the secure two-bolt clamp allows easy micro-adjustments to the saddle position. The seatpost head has also been redesigned for maximum bolt head accessibility, making adjustments more convenient.
The Service Course SL seatpost is available with 0mm or 20mm setback options, providing flexibility for saddle positioning. Its clamp works with all saddle rail types, while the lightweight clamping system complements the carbon construction. The seatpost features updated distinctive Zipp cosmetics and is available in a 400mm length with three diameter options: 25.4mm, 27.2mm, and 31.6mm. This version features a 20mm offset/setback and includes a lifetime warranty.
