Thompson seatpost - enough setback for road bike?
After looking at carbon vs metal seatpost, I decided to stick with metal for now. I like the Thompson Elite but the setback model only offers about 16mm of setback. My current seat post is closer to 25mm setback and my seat is only has a little bit on rails to move any further back. I am concerned that a Thompson seatpost will not give me enough setback and will force me to mount the seat too close to the saddle nose...if it will fit at all.
Has anyone else experienced this situation with the Thompson Elite setback model? How did you deal with it other than get a different post. I am also considering an Easton with more setback. Any other good metal seatpost I should consider?

I have a setback thomson on my ride and I love it. It replaced an Easton which had too much setback. Different fits for everyone!

It's got plenty of setback. It's about the same setback as a Kalloy seatpost (striaght post with trailing clamp).
I use the Thomson on my bike with no problems at all.

if i tell you that i prefer a FSA 32mm setback seatpost, does that mean in your professional opinion that my frame doesn't fit? even though, i find it extremely comfortable...
like I bRAD said, different fits for everyone...
if the thompson setback seatpost will allow you to set your seat at the right point, than use it. if it doesn't, and you need 25mm or 32mm of setback, you can always use an FSA setback seatpost...
actually, the FSA seatback seatpost with 32mm of setback has been on back order at Performance for almost a month, i know because i have one on back order. so, according to clausen, i guess there are alot of people riding around with frames that may not fit...

If you're using a post with more setback than the Thomson and your saddle is already jammed as far back as it will go, forget it. You need a different post. Various models of Easton and FSA offer tons.
You do not want to jack around with saddle position to make a seatpost work. If you do, the next posts you'll be making will be asking for advice on how to fix your knee pain.
I use the Thomson on one bike and it works fine. But then, I don't need much. I don't particularly like the looks of it but the frame had an oddball seat tube diameter and it was the only choice. It would not be my first choice for a standard 27.2 bike.

2 months ago I bought a Flyte frame on auction that came with a 10mm setback post. That thing lasted one ride before I yanked it.

Thomson setback:
Q - How far does the set back seatpost set back?
A - The 10° set back angle gives about 5/8 inch or 16mm of set back.

Yes indeed, everyone is different. I have an Elite on my Caad7 and the lack of setback does not prevent me from achieving a proper position.

I'm sure size has a lot to do with it. I ride a 51-53 depending on TT length. That usually means a 74 degree seat tube so you're pretty far forward whether you want to be or not.

I had a Thompson on a 53 cm 2001 Bianchi XL Ti:

It was just enough setback for me. Very nice seatpost -- easy to adjust, nicely made, clamp never loosened.
Sold the Ti Bianchi and now using the post on my track bike:

Yes, I like Bianchis.

Thanks for the comments. As noted above, I understand that fit is individual to the bike and person. My combo is still not set since I don't have my new seat in hand yet (Toupe...in the mail) so I don't know if I will have a problem with a Thompson setback post or not. My bike has a 74 degree seat tube so that does not help. I have not purchased a seatpost yet. Will wait until I receive my new seat to work out my seatpost solution. However, per your comments, it appears that I have a good chance to make it work.
