Super rare 21.6mm Huffy seat post

Odd size between 13/16 and 7/8”.

10 1/4” long, 7/8” at the top for normal seat guts.

Paint scratches from use.

Huffy used these on several models in the early / mid 80s including the Stu Thomsen and some non-bmx models. Maybe some other bmx bikes too, I’m not sure.

If you need it, here it is.
