Anyone riding a Zipp carbon seatpost?

I had one, just sent it off to my son a few months ago. Very nice posts.

Are you running a poll without actually creating a poll? I have one on a bike. So mark that down, I guess.

No poll. Just wondering what people think of them. The Zipps seems to be well received and have a moderate price, compared to ENVE's and such.

Yes.

I have a Zipp Service Course carbon seatpost, a Whisky 7 carbon seatpost, and an unbranded ultralight carbon seatpost from eBay.

They cost between $40 and $150.
I can't tell the difference.

I have had the Zipp and Whisky on my gravel bike. I can't tell the difference.
I have had the Whisky and unbranded on my main road bike. I can't tell the difference.

The only differences I recognize is the different ways in which each secure and adjust the saddle.

I do not currently own a Zipp carbon seatpost

...however, I was strongly considering getting a Zipp SL Speed carbon seatpost for my forthcoming custom road bike build...except my builder tells me they are no longer available!!!

:angryface:

I am a Ritchey fanboy for CF posts (and a Thomson fan for Ti), but Zipp ones are perfectly fine. Main hassles with seatposts IMO are how you micro adjust the tilt, so be sure to look at that.

That's the straight-forward, no nonsense answer. How do you like the post?

Thanks. I simply cannot help but wonder if the $175 name-brand carbon product is ever any better than the $40 no-name Chinese knockoff. They are all probably made in the same place anyway, mainly. It's just that with things like seat posts and bars I have this overriding concern about things not breaking whilst I'm speed along at 35 mph. Yet I'm wondering is my concern is not misplaced.

It's fine. I think any seatpost from a major name-brand mfr (Ritchey, Thompson, Zipp, Enve, etc) should be fine. As someone earlier mentioned, the main thing is that it has a mounting and adjustment system that you like.

I will note that, while I am not heavy, I do stay away from ultralight items. So my Zipp post (I forget the model) was just their standard cf seatpost back when I built this bike in 2019. (It's probably called Service Course or something like that?)

PS: edited because I just saw your post immediately above. For starters, those cheap Chinese cf seat posts are NOT made in the "same place" as items from Zipp (made in Indiana) and Enve (Salt Lake City); and even if they were made in the same factories, they would have different designs, different QC, different tolerances, etc. My advice: don't cheap out on a no-name, no-reputation item, especially if it's failure could be catastrophic. If you can't afford a first-rate cf seat post, it's better to go with a first-rate alloy model instead.

I think your concern is reasonable, so would stick with a reputable brand and seller.

It was a million to one shot, but my friend’s friend had a CF seatpost fail and apparently the injury to his perineum was quite unpleasant.

The unbranded seatpost isnt a knockoff(Elita One, apparently).
Your wondering is reasonable, but I do think it is important and relevant to clarify that it isnt a knockoff.

As for all being made in the same place, that doesnt mean anything. A factory can build 2 things to very different levels of quality.

I've had really good experiences with the Service Course SL seatpost. 170 lb rider, post has enough flex to add to ride quality but not too much. 2 bolt design, easy to adjust & no slip. I've used both 0mm & 20mm offset. Have them on 3 bikes.

thanks. You scared me with the word "flex". I know I'm being over-cautious, but i think I'm going to stick with aluminum.

I do not have a Zipp CF seatpost.

I do not like Zipp Service Course SL and similar seat posts with an alloy head inserted into a CF tube. Zipp Service Course SL Seatpost Excel Sports | Shop Online From Boulder Colorado. While I am sure they work just fine, it is worth it to me (at 90 kg) to eliminate another potential point of failure. I prefer seat posts where the surface (on which the bottom saddle rail clamp sits) and the post is formed as a single contiguous CF structure, e.g., Cannondale Save (I have two), Syntace P6 Hiflex (I have one), or Ritchey WCS (I almost ordered one). I also dislike seat posts (Basso, Enve, Easton, etc.) with a single bolt through two side saddle rail clamps, which require different clamps for CF saddle rails, and offer less support than a bottom saddle rail clamp.

I would gladly pay the $135 difference to ride with one less thing to wonder about.

You are hardly the first person to posit that a carbon fiber production facility is a natural monopoly. But I don't think so.

You have a beautiful Time frame. Put proper components on it. Don't be the dude driving an expensive German sedan with mismatched knock off tires.

^This. I get it.

Awesome. If not, please further consult: Toseek carbon fiber aero dropbars - Bike Forums

let me just clarify, so everyone understands. Road biking is the best, and it's dangerous. i just can't afford to go down. So many people rely on me. My monthly nut is HUGE. It would be a disaster if I were to suffer a major injury. I purposely avoid all busy roads for that reason. So when I read something about a carbon component snapping mid-ride, I have a hard time shaking the possibility. I know this is a bit paranoid. To the end, I'm gonna get carbon post and bars from a known, reputable brand and spend the cabbage.

I give you props for using this term correctly.

Thank you. The credit goes to my Antitrust professor.

You had a whole course in antitrust regulation? Economics major?

Back in law school.

Ah ha.....circumstantial evidence that we may something in common, professionally.
