Features:Dynamic Chain Engagement (DCE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping. This provides superior chain retention, lower driving sound, increased durability and drag to a minimumHollow gear construction for optimized rigidity, lightweight and durabilityDurable teeth using a plated steel construction supported by a carbon composite (CFRP) carrier bodyDyna-Sys11 HG-X11 11-speed chain compatibleAvailable in 30T/32T/34T
Class-leading XTR 12-speed crank set, integrating the bottom bracket and crank set into a strong, rigid, yet lightweight unit Direct mount chainrings are lightweight and easy to replace while providing increased rigidity, can be set up as single or double Integrated bearing preload design is lightweight and makes installation and adjustments easier than ever Super-lightweight HollowTech II cold forged Duralumin crank arms - hollow design saves weight whilst increasing rigidity and durability Easy to use splined bottom bracket spindle connection provides a rigid and secure interface between crank and spindle With a 52mm chain line and a 168mm Q-factor (1x set up) ideally suited for all-mountain use in conjunction with 10-51T cassette crank set supplied without bottom bracket and chainrings Compatible with all 12-speed direct mount DCE XTR chainrings, please use SM-CRM95 chainrings For use with 12-speed HG+ chains only
