New tires came with the saddle. Manufacturer spec is 230g.
231.7 g and 235.5 g. At worst, 2.4% off spec. Drawing the same inference as in the previous entry (with no extra conservatism), this yields (with some uncertainty about the 3.4): 233.6 +/- 3.4 g, easily consistent with a 230g spec.
I saved less weight than I’d expected simply because my worn tires were lighter than specified by the manufacturer. I’m looking forward to lightening these Kromions further by riding!
Folding tires are a really inexpensive way to pull a little mass (and moment of inertia) out of your bike. Wire beads are heavy.
