I'm learning quite a bit from these responses, thank you! I have a background in woodworking so I'm familiar with listed dimensions not being a true representation. I wasn't sure if that also applied here — now I've got my answer. I tried moving the hanger to the side but still had slippage. It actually seemed less secure. I'm gonna see if the bike shop has some carbon grip since so many people have suggested it.

& it looks like the post is chromed steel too..
What's the significance of it being chromed steel? More likely to slide???
