Shimano's Dura-Ace 11-speed Cassette is comprised of two aluminum cog carriers, 5 titanium and 6 steel cogs (from largest to smallest respectively). This makes for a super-light and stiff cassette for perfect shifting so you can dance up the climbs as easily and efficiently as your chain climbs up and down these cogs.
