You could always nicely ask Jure from Berk composites if he could build you one to your desired specs.

The setback on both my Ritchey Carbon WCS seatposts (2-bolt clamp) measures out to exactly 18mm (center of post-to-center of bottom seat clamp on a 73 degrees seat tube angle)...interestingly Ritchey lists this post as 25mm offset. I just checked the website and it looks like they are offering some sizes of this carbon post in UD finish now.EM3

I suspect there is a lot of aesthetics consideration involved in the decision?

I can confirm this as well; not sure how Ritchey gets 25mm setback...

Ritchey superlogic setback post at 350mm with carbon rail kit and tuned with ti bolt = 162g
Cut down to 280mm or so = 137g - pretty light for something with no weight limit and no specific clamp zone and setback.
Also - looks pretty.

Ritchey does list their 2 bolt clamp 'Pro Carbon' as 15mm offset though.

Hi guys, I need a 27.2mm seatpost with setback (20mm would be nice). Can be pretty short (or I can cut down a long post) so length doesn't really matter. Carbon or alloy is fine.

I'm considering the USE Alien Carbon at ~160g. Anything lighter that you'd consider good bang-for-your-buck? I can't stretch to AX or MFCK prices for this one.

Ritchey Superlogic is pretty light, and the steel bolt can be swapped for ti to save a few more grams...

Maybe it just takes some practice, but I found the USE Alien clamp to be very frustrating to install/adjust.

KCNC is pretty good BFYB:

Woodman also make good value setback posts, but they're much harder to find:

I have had good luck with Ritchey WCS one bolt ... slightly lighter at low 150s.

Thanks guys. Ritchey and KCNC are my "usual suspects" with items like this. In fact, I already bought a WCS Link seat post. On the website (of the store) it was listed as 109g - a bit unbelieveable but I figured it couldn't be much more than 130g or so, considering I'm ordering the smallest size. It arrived and I put it on the scales and it was 224g!!! Plus, there are so many different versions labelled "WCS" I can't even follow what is what!
The KCNC is a definite contender and I'll look into the Woodman, I've seen them in the WW Listings but very rarely actually for sale anywhere.

My Woodman Carbo DX in 350mm X 31.6mm came in at 157 grams. I did have to order it from XX Cycles in France. They were pretty easy to order with and shipping time was a little over a week.

XX Cycles look like they're not restocking the Woodman posts though, same goes for RCZ who also once had most of the options. Universal has zero setback posts but none of the MZ's at all. They do seem to pop up on ebay once and a while though.

USE Alien cyclops. Not the easiest to set up but definitely light and not terribly expensive.
