Any such thing?

I'll have a little bridge rectifier and voltage regulator serving
a bicycle hub alternator (6v 4w) and want to use the bike frame
as the heat sink.

My thought was that, if there's such a thing as heat-conductive
putty, I'd just embed the two components in some of it and stick
it to a frame tube.

Aluminium powder mixed with epoxy might work.

Don't they make thermally conductive epoxy? OP might not want anything
electrically conductive.

Then use zinc oxide with epoxy, that should not be conductive... But
regardless, nothing will work very well, IMHO...
