Anybody have experience with these posts? Wondering how they ride?
My position is dialed in and the difflock mechanism appeals to me if it is as secure as it appears.
Also like the 25mm setback.
Would a 2-bolt design with angle markings give me just as good precision? I like the rail support on the Thomson.

I just put one on my wife's bike. I was surprised how fiddly it was to get the angle adjustment correct. The mechanism certainly seems solid once set up. But I think I'll be sticking with my Thompson and Moots posts.

Maybe I need a course in how to adjust a 2-bolt system or I just had a cheap 2-bolt seat post that is more difficult to adjust than the Thomson mechanism. It took me forever to get it set. I would get the angle correct but when I tightened the second bolt it would change the angle and I would have to go through this process a bunch of times. With the Ionic it looks like I would set it and forget it. I would agree with you if I was working on getting to the ideal position and need to do frequent adjustments in trying to get at that perfect position on the bike. But I already have that and just want to have a consistent and secure setup.

I don't have any experience with the 3T but I have a Fizik Cyrano that I've been happy with. It has a little dial to help with setup. It's easier than the Thomson.

I've found changing the angle with two-bolt seatposts to be very simple-just loosen the front and tighten the rear (or vice-versa) an equal amount. A quarter turn at most. If the angle is set but the clamp is nut fully tight, you have to tighten equally and evenly. Setting fore-aft without disturbing the angle is more difficult, but if you count the number of turns of each bolt when loosening you can return it to the original angle. Again, tighten evenly.

The new design is very nice, I just picked up an ionic 0 to replace a doric 0 (both of which i'm incidentally selling in the classifieds) and its something I would def recommend if your position is set in stone. The new design is a bit awkward to adjust while the 2 bolts can be dialed in on the fly. Another thing to keep in mind is your saddle design - I run my smp with the nose "down", and the front bolt was almost impossible to adjust due to clearance.

The fitter at my LBS said the same thing about adjusting the 2-bolt design; make small turns. The 2-bolt post that I had was an inexpensive American Classic and the front bolt was recessed and difficult to get to. It also was so close to the post shaft that I would often scratch it.
LBS fitter says the .5 degree increments are inadequate, not small enough steps.
Looked at complete bikes and the majority of the Cannondale and Giant bikes had 2-bolt designs, some with a dial adjuster. Also long support rails, some on both bottom and top. Good strong designs.

I liked the IONIC but there was always a little play between the teeth. nothing bad, but it was an annoying sound.
Switched to ENVE...so happy and not looking back.

I hated 2-bolt posts until I tried a Thompson. I find them super easy to adjust on the fly, and easy to keep track of the precise angle.

I just a few minutes ago installed one of these on my cross bike. I agree it's easier than the Thompson. Very nice design. I also like the longish bed that supports the saddle rails.

My favorite seatpost as long as I don't need any setback.
