TSG: Purchase it to use on a bicycle that’s a bit small for me, but the extra length helps me get the right seat height.

rg: I had been using a seat post that was raised too high and therefore quite dangerous since I didn't have enough length in the bike frame. With this longer and well marked seat post, I'm able to pedal with proper leg extension. It's like having a bigger bike. Easy to install , sturdy, and well marked.

PatPat: It was exactly what I needed. Just be careful at ordering the right size. If your replacing your other post, there should be a size engraved on it (picture 1) beause it is not the diameter of the hole. The post is tapered at the end (picture 2)! Go for a size larger than the hole.

Guy Smiley: The seat post is long 450mm 30.9 diameter and light. The matte finish grips into the seat tube perfectly so no slip.. There’s a graduation on the back so it’s easy to set back to your favourite height. I have mine set at 5 for street and 2 for off road. The seat clamp was easy to set and only one bolt. Only drawback is the prominent logo “upanbike”. Nothing screams “performance” quite like upanbike. All in all it’s good value. Im 6-4 with about a 40” pedal reach.

Rags: It’s a really long seat post- so much so that I had to hack saw a portion off. Got it for my gravel bike because the stock one was too short. Though the minimum insertion part is no longer on it from having cut it off, it’s so long that I have most of it in the bike frame- so nothing to worry about. It’s great to see there are other diameters available- I may get another one for my single speed bike.
