Take a Dura-Ace 10 -speed 7900 cassette, add 3 grams and what do you get? The Shimano Dura-Ace CS-9000 Cassette, with 11 speeds! This amazingly light weight was achieved by a few clever design features, including a carbon mid spider carrier and all cogs over 16T being made from titanium. Plus, now with 11 speeds, you get more usable gears in each cassette range.
