    Service Course Seatpost

    For this iteration of the Service Course, the seatpost forgoes carbon fiber in favor of a one-piece, 3D forged design. If you pay close attention to the Grand Tours, you'll notice that this is a reoccurring trend in the peloton. The reason is simple. For the cost of a few grams, the seatpost becomes stiffer, stronger, and more comfortable that its carbon fiber counterparts. In fact, we find that road vibration is better dispersed, while power is better conserved during seated exertions.

    I don't like the adjustment bolts

    This post has a 2-bolt adjustment, which I don't love. The rear bolt is easily accessible. The front bolt is enclosed in a small "canyon" and access is limited. You can't see whether the allen key is engaging the bolt head unless you are underneath the bike. And you can only make very small radius turn on the wrench due to the contraction of the "canyon". If you make too large a turn, the allen key gets wedged in the bolt head and you have to turn it back to remove it. It's very annoying.

    Durable & Reliable, Just a bit Heavy

    Good post at a reasonable price. The twin bolt design is secure, offers nice adjust ability, and helps minimize creaks. My only complaint is that it's a bit on the heavy side.

    I've used it several times

    An ideal post. Aluminum construction is strong and durable and the twin-bolt design is easy to adjust. Maybe a touch heavy buts its bombproof.

    I've used it once or twice and have initial impressions

    Not a lot to say as its intended function is not complicated. Just got this yesterday with my full build. Very, very impressed with the machining and build quality hereof. Highest recommendation.

    Fantastic post for the price

    This is the second Service Course post I've owned and I couldn't recommend it any higher. Obviously there are lighter posts out there but for the price I think it's hard to beat this one. At only 245g for the 0mm offset post this is an incredible deal.

    I've put it through the wringer

    Love what Zipp has a done here. Just a simple, clean looking post with an easy to adjust clamp that won't break the bank. Doesn't get much more straight forward than this.


    Do you really find that aluminum seatposts, being stiffer, are more comfortable? The general consensus is that by and large carbon posts do a better job damping than aluminum. This was backed up by Velo Magazine's testing.


    can this accomodate my 7x9 rail seat ? fi'zi:k kurve
