I do see some options for a 28.6mm but wonder if a 1/2mm or 1mm to 1.5mm difference is too much to properly fit the bike frame without a shim or sleeve of some sort?
Yeah, you need a shim.
It's worth the five bucks.
I just found this on AliExpress:
C$4.82 | MUQZI 100mm Long Seatpot Shim 22.2 25.4 27.2 31.8 33.9 to 28.6 30 30.4 30.9 31.6 31.8 33.9 34.9 36 Seat Post Tube Adapter
I got one so I could use my seat and NCX seatpost on my new ebike.
