Its precision bottom bracket bearings are spaced further apart and are therefore more stable and longer lasting.What's most impressive, is its super-lightweight HollowTech II cold forged Dualumin crank arms deliver an excellent strength to weight ratio, so you can conquer every technical trail without any unnecessary weight holding you back. If your existing cranks are old or worn-out, this is an ideal choice of a replacement for getting back to fast and precise acceleration and shifting out on the trails.Please Note: Bottom Bracket is not includedFeatures: Material: Arm: Super-lightweight HollowTech II cold forged Duralumin; Outer Chainring: HollowGlide Titanium/Aluminium composite Speed: 2x11-Speed Easy to use splined bottom bracket spindle Compatibility: All new XTR chainrings; 11 speed HG-X-chains only 34/24 or 36/26 with a 48.8mm chain line and a 168mm Q-factor ideally suited for all-mountain use in conjunction with 11-40T cassette Please note that the bottom bracket is not suppliedTechnologies:HollowTech: Hollow forged crank arms. A lightweight crankset not only reduces the bike’s weight but decreases rotating mass to aid in acceleration.
