Elegance meets versatility. With the Service Course SL Seatpost, Zipp has placed equal emphasis on adjustability, weight savings and aesthetics. The result is a seatpost which allows you to dial-in that perfect saddle position for comfort and power, while dropping a few grams and adding a little extra style to your race machine.

  • 20mm setback and micro-adjusting downward-facing bolts for a great fit with almost any saddle
  • Shaft and head 3D-forged from a single piece of 7075 aluminum for strength and weight savings
  • Titanium bolts and an intricate machining process drop a few more grams off the regular Service Course model
  • Low profile clamp
  • 27.2mm and 31.6mm sizes
  • 330mm length
  • Claimed weight: 270g.
  • 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.
