Lightweight, correct diameter and nice finishing on the carbon. Great seatpost and seems to be holding up well.

Here you see weights, with seat post clamps (their estimated weights usually exclude that, especially on carbon tubes using aluminum clamps) showing first, my existing aluminum post for my carbon gravel bike (23 Trex FX Sport 6) and this post in comparison. So, I'm saving about 1/4 lb. here and that will be more once I replace the seat. It's not just that it's light though. I also like the design and finish.Most seat posts I've had that have two bolts instead of one for seat attachment have both bolts underneath. This rarely works well. One or the other bolt is usually angled so close to the post that it can't be accessed with an allen wrench or bike tool without scratching up the post. This one has the back bolt underneath and angled well away from the post, while the front one is inserted above. Why is that good? Well, I already adjust my seat by loosening up the rear bolt first, then adjusting the front bolt for angle, then re-tightening the rear. That way, as long as I only loosen the rear bolt to, for instance, take my seat off or adjust it back and forward, all I have to do is tighten that back down and my seat will return to the proper angle, to which my crotch says "Oh, thank God!" 😉 So, this design works for me. Also, if you have a cutout in your seat (if you don't and yet you are buying a carbon post.... why don't you have a seat with a cutout? they are available for both men and women), as I do, you can access the front bolt for easy adjustment using a long allen wrench. Perfect!Finally, the seat height markings are much better than usual, very easy to read, nice!Of course, it would be premature to speak to durability, but it seems solid, does not make cracking sounds under stress from sitting on it, and the finish is very good, so I expect no problems. If I have any, I will certainly update this review.

Accurate 27.2 post to go in an old steel frame to add a bit more resilience to overall rice, nice carbon manufacturing should be a nice permanent addition to a 90's steel frame.
