## Customer Reviews

### ⭐⭐⭐⭐⭐ Clamp
*by S***  on April 6, 2025*

The seat clamp adjusting bolt diameter is small, but works as intended.Time will tell how long the bolt will last.

### ⭐⭐⭐⭐⭐ Great Seat Post Clamp
*by M***L on June 25, 2024*

This product was about as easy to use as a seat clamp can be, with a nice variety of colors. This clamp was installed in minutes and adjusted to the correct size with a few turns of the adjuster. Also, the camp is very nice because of the quick release and adjust design. Overall, a great product and I would recommend this product.

### ⭐⭐⭐⭐⭐ Great quality, fits perfectly
*by C***T on July 13, 2024*

Good quality part fits the tube perfectly. Make sure to measure properly the Seat Post Clamp will be bigger and is sized to the seat post. It would be good if the vendor had something you could print out to size or measure for the correct size.
