I'm not a UCI rider. I'm pretty settled on a fit for a while and done with the bulkier adjustable angle things that come with super extensions.

I'd like to just have an aero stack spacer of some kind that's not already drilled or tapped or anything that I can do with as I please.

Anyone know of anywhere making or having such a thing? I've hunted all over the internet bike related and automotive racing related and even aviation. I've found hollow rod, but nothing that's solid.

To me, somewhere has to make something like this in "bulk" cut-to-length style.

Thanks.
