Zipp's Service Course SL Seatpost delivers amazing adjustability without the extra weight. The ample 20mm setback and micro-adjusting downward-facing bolts allow you to dial-in your perfect position with almost any saddle, and maximize power output with every pedal stroke.

The shaft and head are 3D-forged from a single piece of 7075 aluminum resulting in an impressive strength to weight ratio. The Service Course SL seatpost also uses titanium bolts and an intricate machining process to shave a few additional grams off the regular Service Course model.

Claimed weight for the Service Course SL seatpost is 270 grams. Available in 27.2mm and 31.6mm diameters. 330mm lengths. Available color: Gloss Black and Beyond Black.

Good Seat Post

This seatpost is working well. It is easy to adjust and has me in a better position. It fits my bike well since I don't have a lot of exposed seatpost; a seatpost which angles back would not work. I was having some creaking from my saddle when I was using my prior seatpost with no set back but I no longer have any creaking. I don't know if this is from a better positioning of the saddle or if I have it tightened down better, I had greased the rails when I put it on my old seatpost.
