Good lightweight seatpost. I can feel it damping the road, and it works well with my saddle, a WTB Silverado with titanium rails. It rides comfortable. I think it was a good purchase and provides a comfortable ride that has made it a worthwhile improvement.
Seat post comes with both round and elongated clamping attachments, so you can use seats with conventional and oval carbon rails. It's very easy to set up with a clever system, which uses 2 hex nuts. The seat post is a significant upgrade on the older post with the ridged aluminum seat adjustment service.
It's difficult to give any carbon parts 5 stars for value, but this seat post is well priced for what you get.
