FYI, according to each manufacturer's website, the foldable Ultra Gatorskin in 700x23C weighs 230g, which is the same weight as the Michelin Lithion (also 700x23C and foldable).

My experience is with the standard wire bead Gatorskins, and they have performed flawlessly so far for over 1750 miles.

The Lithion seems like a great deal, though.
