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.
  • Zipp's no-nonsense seatpost to dial in your road bike

  • 6061 aluminum provides great stiffness relative to weight

Sturdy Post, One Piece Design A Plus

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

I installed this on my hybrid bike, replacing a heavy, clunky OEM post that had limited notchy saddle pitch detents. This post was very easy to install, although the front bolt location makes it hard to turn the bolt more than a quarter turn at a time, and I couldn’t fit a 1/4” metric socket onto the bolt. I just tightened the front bolt snugly with a std Allen wrench, then torqued the rear bolt to the recommended 7nm, which also further tightens the front bolt. Weight a bit heavy, but my hybrid already has fenders and a rear rack, so I don’t think I’ll notice the extra few grams compared with more expensive posts. Solid, good looking, and a great value.

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.

I agree completely with your comment on the adjustment bolts. They are awful. I scrapped this post within 30 minutes after mounting it.

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.

Straightforward.

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.

Stellar

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.

Picked this up for my commuter. Solid, economical, and looks great on the bike!

No issues with Zipp

Simple

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.

Can this post be used in a "set-forward" position if flipped around, like the Thomson setback post?

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. http://www.velonews.com/2012/12/training-center/technology/from-the-pages-of-velo-getting-the-most-from-your-post_267560/3
