I find myself with a 27.2mm carbon post I have no use for, and a need for a 31.6mm post. I'm not picky, so long as it's light weight and in good shape.

Mine has no characteristic zig-zags, but it does have some cloudiness in the clear coat from being clamped. No chips, scratches, cracks, or any of that. Only problem is some wear on top of the clamp (where it can't be seen with the saddle installed) from a dude riding a broken saddle for who knows how long on it.

I'm not really sure how to measure setback, but I'm guessing this one is about 25mm, looking center line to center line. 250mm post length. Single bolt. Strongly prefer similar, but what you got?

Thanks!

I've gone to some pretty extreme measures to avoid shims on my bikes, but I've never thought about a seatpost shim. What are the potential drawbacks? Do they tend to slip? Are they ugly? Do they make a shim that doubles as a clamp, for simplicity, and if so, does it come in red?

I shall have to infestigate.

I've got a Cannondale C2 carbon seatpost that's similar to your FSA, but in 31.6mm. You can see it here: https://www.flickr.com/photos/70476053@N00/14416269410/

New take-off condition since I sold the bike with a Thomson to fit the new owner.

What's the length? Trade?

I just measured it at 275mm for the carbon tube section, 300mm to the rails.
