Class-leading XTR Race 11-speed Dyna-Sys 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
• XTR Race chainset uses hollow-bonded construction for the L/H crank arm, shaving vital grams where possible
• Easy to use splined bottom bracket spindle connection gives a rigid and secure interface between crank and spindle
• 38/28 with a 48.8mm chain line and a 158mm Q-factor ideally suited for XC Race use in conjunction with 11-40T cassette
• Hollowglide outer chainring is made with a titanium/aluminium composite hollow 3D structure to maximize stiffness whilst keeping weight at a minimum
• Titanium teeth are used to create a stiff, light weight and hard-wearing chainring
• Compatible with all new XTR chainrings
• Compatible with 2x and 1x set-ups
• For use with 11-speed HG-X chains only
• Average weight 640g (without BB)
