suggestion on seatpost

I need a seatpost with the smallest distance from the center of the
saddle rails to the purely round portion of the post...

and ideas?

Use a traditional "pipe type" post with separate clamp, and install the
clamp upside down.

If you want something more elegant than the post Sheldon suggests, you
can *look* for an old (80's) SR model, or the Simplex post it was copied
from, that holds the post just as low. I've been using one for years on
the rear of my tandem, I can take the rails down to brushing against the
top of the seat tube.

The Simplexes show up periodically on Ebay but in a 26.? size usually.
Haven't seen one of the SR's in years; I *think* the model was called
"P3" but I'm not sure.

Are you talking about vertical distance or horizontal (set back)? If
horizontal, Thomson has a zero set back model. I can't visualize why
you would need less vertical distance since there's always a couple of
inches of seat post exposed. Also note that the distance from the
rails to the saddle top varies (sometimes significantly) from one
saddle to another.

I have a thomson that is pretty low, but is there another with less
(short of a custom ax-lightness)...

?

Similar to Sheldon's idea: I've used a Bontrager Race Lite with the
clamps turned upside down. Click on "View Larger" and imagine the rails
passing across the lower part of the circle:

the offset is fine... the VERTICAL distance is what I am concerned
about...

this is for a tt bike with a full seatmast (seattube goes up to almost
the bottom of the saddle...

I would like to keep the mast as long as possible (and keep the
seatpost as buried as possible...

hence the question...

I don't think I can get much lower than the thompson...

How about an old fashioned round-post with separate clamp combo? That gets
your saddle rails exactly even with the top of your seattube if you want
it. Adjustability in tilt is less, though.

Are those supposed to have the rails above the clamp bolt? I always see
them installed and sold with the clamp above the saddle rails. Well,
except for the Brookses which have the rails going right through the
middle of the clamp.
