Purchased this to replace the stock carbon seatpost on my Canyon Ultimate. The seatpost came in 19g lighter than the listed weight (160g on my scale vs 179g on Thomson's website) and fit into my seat tube as expected. The zero setback is still comfortable and there hasn't been any slipping or loosening of the saddle rail bolts in the first 300km.
The biggest complaint is that there's no markers for seatpost height, which would have made adjustments a little easier, but that's mostly a quality of life gripe.
Using Selle SMP saddles, which are very sensitive to tilt angle. The Thomson head makes adjustment extremely easy yet it stays put exactly where you set it. Also a very light seatpost, and nicely made. I hear that a (16mm?) setback version will come out in the summer of 2022.
