This is the Zipp Service Course SL Seat Post with zero offset. Better fit means better performance. If your saddle is out of position, youíll waste energy with every pedal stroke. That was our foremost consideration in creating the Service Course SL seatpost.  The secure, low-profile clamp allows the saddle to slide farther back along the rails, and with 0 mm and 20 mm setback options, itís possible for nearly any rider to achieve the perfect fit.  This unique clamp design also features downward-facing bolt heads that allow micro-adjustment of the saddle even after it  is mounted.
For high strength, low weight, and efficient use of every gram, the shaft and head are not bonded but are 3D-forged from a single piece of 7075 aluminum. To further reduce weight, the 220 g (275 x 27.2) 0 mm setback Service Course SL seatpost uses titanium bolts and more intricate machining than the regular Service Course seatpost. The Service Course SL Seatpost is available in 330 mm length for the 0 mm setback option and 275 mm and 350 mm lengths for the 20 mm setback seatpost as well as 27.2 and 31.6 mm diameters.

Note: Torque for the seat rails is 7Nm.

Every piece in the Service Course SL line is available in the standard gloss black with white logos, as well as a new Beyond Black color scheme with laser-etched black logos for a stealthy look.
