Offset, 2-bolt seatposts

[MileHighMark]

Looking for an offset (min 25mm) seatpost with a two-bolt clamp that doesn't suck. I tried a Ritchey Pro, but the shaft was a little undersized (I need 27.2mm). Basically looking for advice on models/brands to avoid. I'm especially interested in:

Deda Zero100
FSA K-Force
Truvativ Noir T40

Deda has a really nice clamp(superzero carbon) with easy access to the bolts. I'm assuming the clamp is the same, or just as well laid out on the zero100.

Any problems with it "creeping" up or down?

What do you mean? The angle of the saddle?

Yes. I have a Titec 2-bolt post that won't hold its angle.

Thomson Masterpiece Setback is nearly perfect in every way...except it is only 16mm setback.

Other than that, the FSA-SLK carbon seems pretty good, but a tad heavy. I think it is 25mm setback.

Its fine. I've put about 4k kms on the superzero I have without any issue @ > 75kg.

You only need about 75% of recommended torque. Just balance out the tightening between the two bolts as you go.

Deda is heavy though compared to Ritchey, wouldn't touch deda for any sort of ww considered build. Really disappointing when you put deda stuff on the scale, its always over.

Zipp make a decent seatpost with a solid 2 bolt clamp. They're only 20mm offset though, but the lower saddle rail cradle is extended to provide more support/wider range of adjustment.

Yes. I have a Titec 2-bolt post that won't hold its angle.

How does it lose the angle? Do the bolts loosen? Does the saddle also slip forward/backward when this happens?

I don't have much experience with various takes on Campagnolo-style two-bolt clamps, but it's a very solid design and I'm really curious as to what it takes to make it not function properly.

Have you considered the 3t Palladio? It doesn't have the two bolt design but it's splined so you wouldn't have that angle creep problem and its got a 25mm setback.

It's really hard to explain, so I'll post some pictures the next day or so.
