Review: Great price and fit well - I like the fact that two of them came in the package for under $10. A lot of the other ones I looked at cost that much or more for one. The color matched the original seat clamp perfectly. It fit right over the downtube on my bike without any issues, have used it for several weeks now and I’ve had no issues with my seat post slipping or anything like that so it definitely has a good quality. May have taken all of 30 seconds to easily install it and the quick release makes adjusting my seat up and down , a breeze. Functions just like it should and fit right on the tube. You have to pay attention when putting it on, as one side of the hole is slightly larger than the other one to keep it from moving out of place. The clamp holds very well and is very easy to adjust the amount of clamping force, just by threading the nut down a touch more.
Review: Great price and quality - Great replacement seat post clamps. Good quality, price and installation.

### ⭐⭐⭐⭐⭐ Great price and fit well

### ⭐⭐⭐⭐⭐ Great price and quality
*by A***R on December 29, 2025*

Great replacement seat post clamps. Good quality, price and installation.

### ⭐⭐⭐⭐ It fits, but don't overtighten
*by M***A on July 29, 2024*

It fit fine on my post. However, I think the screw or thread seems a bit fragile. I was experimenting with how much to tighten it and when it was a bit too tight, it felt like it was about to break. I didn't force it so nothing bad happened but it doesn't seem as robust as the OEM quick release clamps I have used in the past. It's good that it comes in a pair as frequent use will probably wear it out.
