How do you figure, exactly? A Surly fat tube weighs 310 grams. Revoloop even makes a
159 gram fat tube. 8 ounces of sealant weighs 227 grams, plus a few for a valve. So the difference is not large even before we account for the difference in tire weight between a tubed-only model and a typically-heavier tire that can be run sans tubes.
Many people assume that going tubeless saves weight, but it rarely does.
