Shimano XTR Hollowtech II Chainset FCM970

Class-leading XTR chainset, integrating the bottom bracket and chainset into a strong, rigid, yet lightweight unit.

Key Features:

• Integrated design makes installation and adjustments easier than ever
• Precision bottom bracket bearings are spaced further apart, and are therefore more stable and longer lasting than conventional bottom brackets
• Super-lightweight HollowTech II forged Duralumin crank arms - hollow design saves weight whilst increasing rigidity
• Silver crank arm face for lasting good looks
• Easy to use splined Octalink bottom bracket spindle connection gives a rigid and secure interface between crank and spindle
• The middle chainring is made of titanium supported in a carbon shell which combine to produce a hard-wearing, light weight, and stiff set up
• Development has resulted in stiffer, light weight and hard-wearing HyperDrive 7075 aluminium outer and inner chainrings with a highly durable Nickel-plate treatment
• Conventional 104 / 64 PCD four-arm chainrings 44/32/22T
• For use with Super Narrow HG chain
• Average weight 747 g (175 mm including BB)
