Reviews
The EC70 Seat Post came on my Cervelo Asparo bike which I purchased in 2022. The Seatpost hold down clamp failed after about 3 years of riding. Fortunately I did not crash when the seat came loose. I replaced just the hold down clamp and then a month later the bolt holding the clamp failed.
After the two failures, I decided it was best to replace the entire seat post. Which is the review you are seeing. The replacement was easy and have not had any issue in the month since installing it.
I ride the bike every Saturday with our local club. Its early use saw some gravel, but the last three years are road only. Unfortunately since the hurricane (Sanibel Island) there are some rough spots in the road and paved paths thatI have hit fairly hard a few times. So I am assuming one of those hits caused some hidden damage.
I have been riding for over 1 year with this seatpost. It was an excellent decision. I would purchase again. Dampens bumps, increases comfort, and saved a fair amount of weight at a reasonable cost.
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.
