215 lb rider, post creeks every now and then but not all the time. Love the fact I can loosen the seat separately from tilt adjustments. Have about 400 miles on it, so far its holding up to my weight. Kinda hard to find flaws in anything Easton makes.
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.
