Shimano's Dura-Ace 10-speed Cassette is comprised of an aluminum cog carrier, 4 titanium and 6 steel cogs (from largest to smallest respectively). This makes for a super-light and stiff cassette that makes your derailleur shift like a dream so you can dance up the climbs as easily and efficiently as your chain climbs up and down these cogs.
Note: 10-speed cassettes require the use of 10-speed chains.
For optimum shifting and braking, Shimano 7900 Dura-Ace components are best as a system (they're not recommended for use with previous versions of Dura-Ace).
Weight: 163 grams (11-23)
The cassette lockring is included.
