Key Features and Benefits:

• 2-piece cap-free design: Reduces weight and increases stiffness compared to traditional assemblies. This design improves power transfer efficiency, giving you a more responsive and stable ride.
• SG-X chainrings with pick-up pins: Designed with strategic tooth profiling and lift points for quick, precise gear changes. This results in smoother transitions between rings, especially under pressure.
• HollowTech II bottom bracket compatibility: Uses a wide bearing stance for optimal load balance and crank rigidity. This enhances drivetrain stability and pedalling efficiency.
• Lightweight aluminium crank arms: Built from anodised aluminium for corrosion resistance and reduced mass. The lower weight reduces fatigue on long rides while maintaining strength and reliability.
• Triple chainring configuration (50/39/30T): Offers a wide gear range for climbing and descending with ease. This versatility helps maintain cadence and comfort across mixed terrain.
• 4-arm 110mm BCD design: Delivers improved load distribution and consistent torque through the pedal stroke. This maximises drivetrain life and maintains reliable performance over time.
