The M770 is hard to beat - durable, lightweight, stiff, and providing excellent shifting. Modern mountain biking demands a lot of its components, and the XT M770 delivers them flawlessly. The carbon composite middle ring serves a variety of functions - it adds rigidity and life to the ring that most riders use most. Plus, its stiffness and machining provides excellent shifting into adjacent rings when the extra help is needed.
Hollowtech II bottom bracket system adds rigidity and stiffness not only to the crank, but to the entire drivetrain. Improve efficiency and reduce weight by moving to the system that places bearings further out on the frame for ultimate performance.
asked by: lamdman1976 can i use this crank for a 1X10 system?
A.
anwered by: canteau You can but you will need to change the chainring to a 10 speed compatible single speed ring such as the Salsa or Niner chainrings.

Great all-around cranks. Fairly light, very strong, top quality and oh-so-pretty! I've ridden these hard for over a year now. They are outstanding for their intended purpose and a great value. Buy without fear.
