The 11-speed Dura-Ace rear derailleur has been redesigned for lighter operation with the help of new low-friction polymer-coated cables. Shifting effort is now more even across the range, with similar force required at both ends of the cassette.
- New spring mechanism for lighter, shorter and more equal shifting operation
- Carbon pulley plate
- Wide link design increases rigidity, reducing deflection for precise shifting and a long service life
- Bearing equipt guide and tension pulley
