29.4 down to 26.8 seatpost shim - does it exist?

As per the title
Anyone know if anyone offers these?

I think you'll struggle. Could you try a 27.2 to 29.8 and sand a little out of the slot? It takes up the same 2.6mm difference and is only 0.4mm bigger so should conform when all clamped up. Especially if you use a thermoplastic USE one.

Perhaps this one? https://midwaybike.com/product/seatpost-shim-26-8-mm-to-29-4-mm-alloy/

Use has tons of shims but they start from standar measure to rare ones, for example the 27.2: https://www.ultimateuse.com/products/27-2mm-i-d-shim 27 different shims

That first one is perfect
Tho it looks like you need to be a US dealer to get it

I use a 27.0 post in a 29.6 frame. I tried a couple 27.2-XX options. Works fine on and off road for many years now.

thank you. I know a shim will work fine. I'd prefer not to use one but I have a 26.8 Moby in black for my FAT Ti and wanted to try that in the 29.4 seat tube. I'd assumed that finding a shim would be easier than finding a 29.4 Moby
