I wish, Ray! It’s the way the post thickens at the top; you can’t force it any lower.

Leah,
   Would cutting a couple inches off your seatpost solve your problem?
A 350mm long seatpost is pretty long and likely intended for frames with very extreme slope to the top tube
Standard Rivendell issue seatposts measure 250 mm from the seat clamp to the end of the shaft. 
350mm would add approximately 4 inches to the length. 
Does that help clarify your question?

Leah,

I do not know an answer for your question. I did own an older version of the IRD Wayback seat post only to discover that I could not get the seat post down far enough to my liking on my Clem. I sold the post.
My next move was to find and buy a Sakae Ringyo MTE-100 27.2mm post with a shim to fit my 29.8mm seat tube.  I have had these posts on other bikes of mine in the past. I did find one on eBay late last year and bought it. It solved a number of problems for me. One was the amount of setback I wanted and secondly, I could set the post down a lot farther than I could than with the IRD Wayback post.  I remain very happy and pleased to this day with my long torso and short limbs.

May I suggest that you buy a Sakae Ringyo MTE-100 seat post off of eBay with a shim. I do not know how much setback you need. I know it may not be the most pretty post, but it solves some problems that I had.


Trying to help.

I put a piece of white tape on the upper part of the post to mark as a stopping point of insertion as shown in the picture.

Does anyone know if you can get the seatpost lower with the new design? My IRD post from Riv needs 5 inches and I’ve got it totally slammed. It would be nice to know I had a post I could put a little lower. Also, the product page shows lengths of 250-350mm and the way I read it, it is measuring the shaft of the seat post, not the setback? How would one know which length to choose?

Very Good Max !

I got the Soma email that showed the seatpost and noticed it looked different, as it was. It's been redesigned with a new forged head and now is 30mm setback rather than the 50mm.

Just so anyone ordering the post understand IRD doesn't make the previous version anymore. Read the fine print !

Things are working for me without swapping seatposts and simply by pushing my saddle forward instead of backwards.

If anyone is still looking, the IRD posts seem to be back at Somafab: https://www.somafabshop.com/shop/ird-seatpost-wayback-compact-6972?search=compact#attr=346,4463,1073

I'd guess it's working out for Max since he hasn't posted an update, that's usually how it goes when all is well !  

I can't say bike fitting is mysterious, I'd call it intuitive. While others can help steer you in the right direction, the fine tuning is all an "inside job", so to speak. Just as no one can eat or breathe for another, the Life that Lives In and As ALL isn't up for "negotiation". It MUST BE ! 

Since I've been re-familiarizing myself with riding in road position with DT shifters and new saddle, I've moved mine forward some 15mm+ from when I started with it. It just keeps feeling better, as in more efficient/effective use of what strengths I have. Yesterday I unexpectedly found myself riding up a knarly hill that has some really steep sections. I had not ridden it in a long time and surely had my doubts as to doing it. It took a while to get in the groove and took to standing on the initial very steepest parts, but soon found myself seated and going up just fine in the 36/32 high gear. I used to have to stand the whole way. I could feel how much more effective it is to be able to use the quad/front muscles more by sitting more forward. When I was too far back I'd have to either stand or go to a lower granny gear and felt weak. My road bike doesn't have a lower gear and thankfully so. I didn't need a lower gear to compensate for my self-made mistake, I simply had to express my inherent strengths most effectively and efficiently, upon which it often feels effortless. Rather neat in that way ! I'm riding 150mm cranks and somewhat mid-foot pedaling, all of which just works well for me.
