Review on 🚲 UPANBIKE Bicycle Seat Post - 13.8inch (350mm) Aluminum Alloy Bike Seat Post with Micro Adjust Clamp - Available in Multiple Diameter Sizes (25.4, 27.2, 28.6, 30.4, 30.9 and 31.6mm) by Jon Smith

This seatpost is amazingly good quality for less than $20. The tolerances are right, the head screw turns easily and the finish holds up well even after adjusting the post several times. I used this on a Lectric 2.0 bike to replace warehouse junk. It fits great and stays in place. I chose this post because the clamp is behind the post, which allows the seat to slide further back. The seat in the Lectric feels way ahead of the pedals, and that helps address that issue.
