Three alloy carriers & 5 titanium sprockets make this Shimanos lightest 10-speed Dyna-Sys MTB cassette Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates resulting in a crisp smooth shift even under load Close ratio gearing allows a more efficient use of energy through finer cadence control Three separate lightweight alloy carriers reduce weight & increased stiffness giving more precise faster shifts Five largest sprockets are made from titanium to reduce weight without sacrificing strength Sprockets are cut away extensively & drilled to further reduce weight without reducing rigidity Nickel-plated finish offers hard wearing resistance to corrosion Alloy cassette lockring For 10-speed HG-X MTB chains Average weight 255 g for 11
