🚲 UPANBIKE Adjustable Bike Seatpost: 400mm Length, Multiple Diameter Options for Mountain Bike and Road Bicycle Review

Great colour, easy to install and tough enough for touring and moderate terrain use. It comes in one size, 27.2, and everything else needs a shim but haven't used it yet.

Beautiful workmanship, easy to install. I had to cut off 70mm to allow mine to slide down far enough for my height... My aluminum frame has a weld in the down tube.

I installed the seatpost right at the minimum insertion line and noticed a slight flex about a month after using it on easy trails. Gradually it got worse and now I have to remove it for fear of breaking it mid-ride. The ad says Aluminum 7075. I'm not sure. I'm heavy but within normal range at 225lbs.

Not as shown. Completely different head on the seat post. I ordered a two screw model which has more adjustments than the one screw model. My existing seatpost is a single bolt model and doesn't adjust level - it only tilts a degree or two and hurts my crotch! I thought I found a solution before this weekend's Ragbrai trip - - WRONG! They pulled bait and turned me on! This is not the seat post pictured or the one I ordered! Check out the photos!
