SRAM's Force DUB 12-Speed Crankset provides a wider range and closer steps between gears fundamentally changing our previous concepts of road gearing. Its smaller chainrings feature a consistent 13-tooth gap between size variants for smooth dependable shifting while X-Range gearing technology allows for a smoother progression that improves cadence efficiency and ensures we are in the proper gear. The arms are constructed of carbon fiber helping to provide exceptional strength and stiffness while dropping weight while the DUB bottom bracket combines stiffness and durability to create a complete system for the best drivetrain performance.
