It features super-lightweight HollowTech II Duralumin crank arms and direct mount chainring compatibility.
SIL-TEC Chain Treatment: Applied to the super-narrow, hollow-pin XTR 12-speed chain, SIL-TEC (PTFE plating) vastly increases durability and ensures incredibly smooth, low-friction running, perfectly complementing DCE chainrings and Hyperglide+ cassettes.
XTR 12-Speed Cassette: Choose between the lightweight 9-45T (compact) for efficient XC/Trail riding or the expansive 10-51T (wide-range) for ultimate climbing prowess and finer cadence control. Both are built with a blend of alloy, titanium, and Chromoly for optimal weight and durability.
