Gear Shifting System

• Wireless communication between gear levers and derailleurs.
• New Di2 servomotors with a more compact design.
• Rear derailleur shifting time reduced by 58%; front derailleur by 45%.
• Charging port and integrated radio transmitter built into the rear derailleur.

• New 12-speed cassettes are compatible with existing 11-speed freehub bodies.
• Cranks available with integrated power meter.
• Weights: Dura-Ace power meter crank 748 g — Ultegra 769 g.
