Looking for a 13/16" shim for a Trail a Bike
I want to hook my Trail a Bike to my old Schwinn but they no longer offer the 13/16" (21.15mm) shims. I know they used to. Do any of you have one laying around?
Thanks.
Thanks.

I made mine work with a pvc pipe cut lengthwise to allow it to squeeze and an old tube for friction. If your connection doesn't lock tight on the seat post, but rotates around it, maybe just a pvc pipe?

A shim is a common machine-mechanics technique,,
you need know ID and OD and the difference between the 2..
then halve that .. and that is how thick your shim needs to be.
OD-ID/2

Yeah, it's just such a fat shim that the factory part would work better than any of the cludges that I've tried so far.

I use the trail a bike hitch on two different bikes, and also had success with a short piece of PVC pipe slit down its length. Using the shim on one bike and the PVC on the other was a lot easier than trying to switch it all each time.

I checked and I do not have the shim you're looking for. Sorry.
If it is absolutely critical and the previous suggestions don't work , find a PVC pipe with the correct outside diameter, and a machinist can put it on the lathe and mill out the inside diameter to the appropriate size.
