UPANBIKE Bike Bicycle MTB Replacement Extra Long Seatpost Seat Post 17.7inch (450mm) φ 25.4 27.2 28.6 30.4 30.9 31.6mm

You get what you paid for. Looks cheap but it gets the job done. Ive been using this for 2 years. No problem or whatsoever. Its good seatpost

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.

Does what it supposed to do

Es difícil de encontrar la medida que adquirí y cumplió con las expectativas

I extensively looked for a Replacement Extra Long Seatpost Seat Post. And deceided on the UPANBIKE Bike Bicycle MTB Replacement Extra Long Seatpost Seat Post 17.7inch The 25.4 I ordered was an absolutely perfect fit and at 17.7 inches long, it gave an inch or two more than any others I reviewed. I didn't go wrong. Actually, the UPANBIKE is a much better post than than the one my bike's manufacturer was selling on Amazon. In addition, you can adjust the seat sitting position a few angle. The photos on Amazon show how easy it is to install. No issues whatsoever. Very satisfied with this purchase and a black post goes with any color bike. I am very satisfied for the quality, length, and price value.
