Seatposts with more setback / offset

Using shims should be no problem.

The Thomson setback post that is angled back provides 16mm of additional setback compared to a regular post, not 16mm total.

Thanks JohnM. The Thomson setback posts (like my Ritchey) look to have the front of the clamp in line with the centre of the post. I just measured the Ritchey and it is ~ 20 mm setback from the centre of the post to the centre of the clamp, so the specs I had found on the web didn't match up there.

The Easton EC70, even though they are listed at 25 mm, look to be ~10 mm further back than the Ritchey (more setback and shorter clamp), so this might be an option:

I'm looking at going with one of the FSA seatposts (mentioned in the first post) but am trying to find out a bit more about them. I sent an email to Bikewagon.com and their ebay store (where I would be buying from) on Monday but got no reply. I am in Australia; if anyone in the USA would be so kind as to phone them for me, I would be very grateful if you could find out:

- Do both of these seatposts use the same clamping mechanims?

- Both of these are listed as having 40 mm setback, but from the pictures
the K-Force Lite does not look to have as much setback as the SL-220: do
they both actually have 40 mm setback?

Their toll free number from Canada and all 50 states at 1-877-bike007 (1-877-245-3007).

Edit: I am looking at:
- FSA Carbon K-Force Lite 31.6 x 250 with Shim (Product Code: F192-0020-316)
- FSA SL-220 Micro-Adjust Al 31.6 x 250 (Product Code: F192-1030)

I have one of those FSA carbon posts with a pretty extreme setback. Top quality product. I use it on my crit bike which is a tad on the smaller side, shorter top tube.
