UPANBIKE Bike Seatpost Aluminum Alloy φ27.2 30.9 31.6mm*400mm Extender Length Seat Post for Mountain Bike

Was having a problem with my standard carrera vengeance seatpost the the seat bracket kept moving and moving the seat back ,so decided to get this ,night and day difference especially with it having two bolts as soon as I sat on the seat you could tell right away how solid everything was

It nice and lightweight when I received it had a little scratch on the seatpost it didn't really bother me too much that kind of to be expected for the price thoughThe installation was quite tricky I found you will definitely need patience I tried 3 times the 1st time couldn't do it so I tried with a different set of Allan keys and managed itAs the seatpost is very long mine was 400mm I had to cut mine using a pipecutter down to 320mm now it fits flushAlthough with these issues I would still recommend the seatpost

Bought this due to my son's seat constantly coming loose. I was very impressed with it, nice piece of kit, my son loves the colour that matches his seat, and the seat is now secure and tight! I was tightening it on a regular basis but haven't had to do this for some time since fitting this.

Fits well saddle clamp easy to set to desired angle, there's an allen key to accompany the post but it's the wrong size.Product is quite light.

Perfect Replacement for Diamondback Sync 1.0 Mountainbike after the seat bracket broke. Followed instructions on how to get measurement and ordered the 30.9mm which fit perfectly. Great quality item.

got the blue one at 31.6mm wide. Good quality for the price but e x t r e m e l y heavy.

This is an in-line seatpost. Couldn’t really get the. Correct angle for my saddle. It has a two bolt system and the bolt nearest the top tube had to be done up nearly all the way, this caused the bolt to bend after use.

Cheap and cheerful bike seat post in 30.9mm fitment, feels well made and light for cost
