Works great!
I was skeptical that it would fit ok given the very small diameter difference, but it works great! No seatpost slipping at all and I now have a dropper post I otherwise wouldn't have been able to use.

Works perfectly
Worked great so I could use a 30.9 dropper in my 31.6 frame. My only concern is water and dirt going down the crack so I'll probably put a little silicone there to prevent that.
