Thx... That would make sense then. I think without the grooves, it's just slick metal to metal at an angle to hold into place at the washer. I rode most of the mini-test in the drops. I'm sure that put more weight on the washer. I'm glad you mentioned the FSA brand. When I did some limiting searching for a carbon post with a different design, I saw one you were talking about. But didn't know the brand. And couldn't see if it had the grooves in the clamp by the pic. I did do some reading on the triangles as well. That's an alternative I didn't know existed. None of our lbs seemed to have anything like that on the floor. Or ever even mentioned it as an option. Sometimes I think it's just dependent on the help at the time.
