27.2 Seatpost 400mm LITEONE MTB Seat Post with 28.6mm 30.9mm 31.6mm Seatpost Shim Suitable for Mountain Bike Road Bicycle MTN BMX ( Include 3 Tube Adapters 15mm Setback )

Bought a new e bike and the seat was very uncomfortable and the adjustment was an old school 2 bolt clamp onto the seat and get what you can as for adjustment. So, I picked this up and it arrived the next day. Slipped in the shim and then the seat post to make sure they fit then added my saddle {seat} and went for an adjustment ride. Didn't need to adjust. The two bolt adjustment on this seat post worked perfectly for my needs. Even the saddle that came with the bike felt more comfortable. Waiting for my new saddle.

I’ve built dozens of bikes, but I could NOT assemble my seat rails to this post. It was ridiculously complex and I found it impossible, and so had to return the seat post.

Even though they have 3 of the most popular current seat post diameters, my old electric bike from the 90s had a different size. So do use calipers to check what adaptor you really need.

Built well and sturdy. Milled from a solid piece of aluminum.

This is NOT a Zero offset seat post.Be warned.
