Has anyone used a 30.9mm diameter dropper with a sleeve? Is there anything stated anywhere that it wouldn't be ok to do? I have a spare dropper in this size and it saves me buying another if I don't have to @leo_kokkonen
The issue with using a dropper shim is that all of the force placed upon the dropper is concentrated in to about 4" (the length of the sleeve).
Of course, no other manufacturer minds...
