Review on 🚴 Premium 3K Carbon Fiber Bike Seatpost: 27.2/30.8 Dia, 350/400mm Length, Ideal for Mountain, Road, BMX Bikes (Black) by Brian Wolf

Seat post worked great. I experienced an unexpected flex, but it softens the bumps. I'm 220 and 6ft 1in so I pushed the post a bit out of frame, I have 400 vs 350 to compensate. It is ideal for sleeve 27.2. I rode about 7 miles on a fairly aggressive solo course and completed the jump course with the kids with no issues. The two-bolt adjustment was easy and held the seat securely in place. The weight may be slightly less than my old aluminum bar. To be honest I was a little surprised buying the quality. Time will tell if it holds up but I'm happy with how it rode yesterday. I'll keep an eye on it when it goes down.
