FC-M970: Hollowtech II Crankset

Incorporating the benefit of rigidity with minimal weight of the Hollowtech II combined bottom bracket and crankset system, the new FC-M970 manages to drop even more weight while increasing shifting performance and durability

• Patent-protected chain ring design means unmatched shifting performance:
Market standard front shifting performance (when combined with a Shimano front derailleur) is taken even further by the precision molding and machining of the composite carbon fiber and titanium middle chainring and greater rigidity of the outer chainring.

• Enhanced durability
The titanium teeth of the middle chainring along with Ni plated the double anodized chain interface surface of the outer ring combine to a conservative 100% increase in durability over prior generation XTR chainrings.

• More precise bearing adjustment
The new left hand crank arm mounting system provides a higher integrity solution that creates more precise bottom bracket bearing adjustment, extending the bearing life while keeping rotating resistance to a minimum.

• Lighter weight and more versatile
Even with all of the additional benefits over prior generations, the new FC-M970 shaves even more weight from the current model thanks to the composite carbon fiber / titanium middle chainring. The 44-32-22 rings also share the same bolt pattern as other popular Shimano cranksets such as XT and LX.
