Review on 🚲 FOMTOR Adjustable Bicycle Seat Post 25.4/27.2/28.6/30.9 x 350mm - Alumium Seatpost for Mountain, Road, and BMX Bikes by Robert Espinoza

It does what it's supposed to do, supports my seat (and me). There was a small problem with the size. The original Diamondback seatpost was exactly 27.2mm. There was nothing wrong with the mechanics of the Diamondback, it just had one damper which I despised, so I needed a regular straight seatpost. This replacement was 26.6mm. I had to modify the clamp slightly and using a grinder slightly widen the gap on the bike frame. Once that was done, he worked like a champ.
