Looking for recommendations for aftermarket carbon seatpost
 

I have an older Giant TCR. I'm looking for a source to buy a carbon seat post. Preferably a more aero design but round is ok if it's good.

What does your frame take? Posts with an aero upper section and round insertion section are few and far between.

It is a round post. Looking for the hard to find version. I have an older Bontrager carbon post, but the metal saddle mounts and hardware are heavy and ugly chrome look.

I am a huge fan of the FSA SL-K ITC post, but it's getting pretty hard to find in anything other than 31.6x350. The three-bolt head should be adopted by everyone, AFAIC.

I like the Fizik offerings. For some reason the R1 model disappeared, but if I wanted to spend the money, the R00 seatpost would be what I do.

FSA K-force. Great post.

Fabric Scoop.

I have several of the FSA SL-K seat posts. As was mentioned before, the three bolt head is easy to adjust and it does not drift out of adjustment. I am OK with either a two bolt as done by Thomson or three bolt adjustment seat post. If the angle adjustment is not secure, like all the single bolt posts I have seen, I would stay away from them. I had a lot of trouble with a Ritchey single bolt post on our tandem slipping out of adjustment before I gave up and bought a Thomson post.

I did have one SL-K shear off on my hard tail trail bike a couple of years ago when I landed a little hard off a jump. I still ride on the one on my road bike. No issues there. Just not up to the beating I gave it riding off road.

At the time I was maybe 250 pounds. FSA did not publish a weight limit for the post. FSA did warranty the post, but they insisted that it was cut by a sharp ridge on my frame. The frame was a Lynskey and there is no sharp ridge on the frame. I replaced the mountain bike post with a Thomson, which is in my opinion the best aluminum seat post I have seen.
