Got this to secure my seat a little more than the stock QR seatpost clamp on the Rad Runner. Worked well, and the logo was discreet so it looks stock.

Needed to replace the factory quick release clamp on my cheap bike because it wouldn't clamp down hard enough on the seat post. This was the cure for that problem.

I had to repair an E-bike with an odd problem. It seems that the built in seat post clamp wasn't able to hold the seat post firmly enough and each time the rider put their weight on the seat the seat post would slide down into the tube making it too short for the rider. This 31.8mm clamp was just the right size to fit the seat post perfectly so I just slid it onto the seat post and tightened it in place to stop the post from sliding down into the tube. It worked perfectly and now the rider is happy once again. Thanks for a great solution at such a reasonable price!

It's a cheap clamp. It clamps cheaply.

Nicely made clamp at a good price. Also like that it uses an M6x25 bolt, that has much better clamp capability than an M4 bolt that most other post clamps use. The bolt itself is junk soft metal. I stripped it on my initial install. Luckily I was able to get it off and replaced it with a stainless M6x25mm hex bolt from my local Lowes.
