💪 Enhanced Performance with Promax Seat Clamp Bolt - Quick Release Feature (Black) Review

Wanted to attach a bicycle seat post with it. It's too weak. The screw size is too small. And the price is too high. Shopping spree.

The length of this bolt was much shorter than the Sunlite bolt I was looking for because the Sunlite pinch bolt touched the inside of my leg when I was pedaling. Not only is it shorter than my previous clamp setup, it's lighter too! The price I paid was great and shipping was fast and free! The only…
