As cassettes go, it doesn't get better than this.
- Shifting has been even further improved by creating an even more rigid (and lighter) aluminum carrier unit along with re-engineered tooth profil
- Cassette design is lighter as Shimano has developed a super lightweight and rigid aluminum cassette sprocket carrier
- The largest four cogs are titanium and weight is reduced by 10 grams
