Hi-E Rims as described on Velo-Pages:  “213 grams - 2024T4 aluminum alloy sheet doubled on the inside and attached with hollow rivet eyelets - 20 mm section - box profile - smooth / non-machined braking surfaces… these remarkable rims were manufactured from flat sheet stock aluminum which was then extruded to form in much the same manner as modern seamless gutters are fabricated]”

Sure enough the weight is low. REAL low.  I’m hoping my carbon KOM hoops come out this light and those were made around 2008.. whereas these HI-E’s were made in the 70s.
