So I have been posting on this forum trying to get advice so I don't do stupid mistakes/waste money. Looks like I made a stupid seat post mistake and hoping to be able to send it back to Amazon.

I wanted to try and lighten my bike some more so I bought a Syntace P6 carbon seat post. The kicker is that it doesn't have the 25 mm set back that my stock Raleigh seat post was. I only gained a 2 oz weight loss also. With this set up on my bike it now moves me a 1/2" forward on the pedals and the reach is also I think 1/2' short.

Is there a carbon seat post out there with a 25 mm set back?

Thanks
Zman

Not only did you buy a carbon post, you bought the most expensive carbon post :)

Lots of carbon out there. Measure our approximate setback of your old post and hit the e-shops. Most are 20mm setback from my experience.

I run a zero sb so am in the smaller group that wants a straight post.

You should have measured your saddle height and setback from the B.B. centre before you pulled it. Did you?

I have had my roadie bike Lemond Victoirre pro fitted many  years ago and the fit works good. I set up my 2 gravel bikes off this same fit and it seems to work ok for me. Yes the LBS did measure the seat height from the bb center. My trouble is he measured the setback on the stock post and it was 25 mm. My Brooks Waterford saddle won't slid forward enough and so it's 1/2" short from the stock set up. I did get a deal on the post at around $66-$75 if I remember right but seems like not a deal at all now.

Interesting. Seat tube angle of the frame will determine how much setback (or none at all) you need on a given bike. I have short femurs and need 74deg angles to get knee over pedal as well as shorter 170mm cranks. Sounds like you have a good idea of what fits you though.

That being said, I’m very interested in a Syntace P6 and if you’re going to sell it please let me know.

Hey Zurichman, 

I don't really have a carbon setup recommendation. Next time, can you please title it something like "Carbon Setback Seatpost?" or just continue on the other thread with the same name that you started? Thank you. I appreciate your participation on here.

I talk to a LBS wrench/owner at a Bicycle Club Membership Party last night and he said there was all kind of seat post 25 mm set back and was to get back to me but no reply yet.

The size I need is 27.2 mm I also don't need the most expensive seat post out there. I might enjoy some dampening of the seat post but open to all suggestions.

He threw out some brand names

Specialized
Reynolds I believe

Thanks for any and all suggestions
Zman

I did the survey thingy to just get some ideas of what people use. Could you please if it isn't too hard give me a guess of the cost of your seat post and whether you got a deal on it like Amazon, Art's Cyclery or any other source. This is all new to me.

Thanks
Zman

I use the Canyon VCLS 1.0 seatpost. Infinitely adjustable setback and provides way more compliance damping than almost every other seatpost out there.
