CYSKY Bike Seatpost 27.2 x 400mm with 4 Size Bike Seatpost Shim 28.6mm 30.4mm 30.9mm 31.6mm, Bicycle Seat Post for Mountain Bike Road Bike MTB BMX

Man this is a great deal!! Greatest seatpost I ever had 400mm.. more than enough for my e scooter, the post has ridges on it for grip and it's the easiest time I had putting the seat on the fastest I've gotten the seat on no struggle and to top it off 4 adaptors ..better get it now B4 it's gone😀

Worked good was a little tight with the smallest shim and to loose with out shim. Had to use a rubber mallet

Working perfectly

Perfect

The item is packaged using a thick plastic packaging material while inside a bubble wrap. It fits nicely, without using the adapter shims, on my cheap Mongoose model R4154TGA. The model number can be seen on the sticker attached on the bicycle. So far good. I can't comment on the quality of the metal used since I just got this yesterday.

Nice looking, had ribs on the side which is great for holding the post in position, the stock seat would slide done while riding, this will work correctly. The mount was different from the seat I bought to go with it, and I had some difficulty making it work, it was not easy, it would be easy for a bike person used to this design.

Did not fit

I am 6’4” On my e-bike I needed a taller seat post so my legs could stretch out. This seat post was tall enough and it has a built in shock absorber to make it more comfortable on your bum. I would buy this again .
