UPANBIKE Bike Seat Post Aluminum Alloy Length 350mm 400mm φ25.4/27.2/28.6/30.4/30.9/31.6mm Black for Mountain Bike Road Bicycle

Made well. installed perfect

My bike had its seat AND seat post stolen a few months ago, so I replaced them recently. This seat post is easy to install, and the calibrations along its length make re-adjustments more convenient in case I let someone else ride my bike and they set the seat at a different height.

Very strong but didn’t fit but I’m sure I’ll use it in the future since I been repairing bikes and some are missing parts like this

Make sure you order the right diameter check twice with calipers.

Great

Easy to install and very sturdy

I love it

Please don't purchase this product if you expect it to fit your bike. It is advertised as 25.4 mm in diameter. As you can see on the attached photo, my caliper shows it is 23.8 mm. There is no way you can tighten the post. I should have read previous posts about this item. I had to select 1 star in order to leave this review but the product deserves 0 stars.

Great product fits the e bike perfectly

25年前の折りたたみ自転車の、サビサビのポストを交換しました。とても軽くサドルの高さのメモリもあるので、良い感じです！

最初はキツいかなと思いましたが、無事に自転車本体の接続完了付けてみてカッコイイと思いました。気分転換にもお勧めです

Got sent the wrong size but they replaced it with correct one.

I purchased the 27.2mm size. I like the fact that it appears rugged. 3mm thickness seems thin, but it isn't. It feels indestructible once you see it for real. I weight 220 lbs and I have no doubt this bike seat extension bar will support me. In fact, I use it to extend the seat of my spinning bike and it works perfectly.
