Shimano Dura-Ace Di2 RD-7970-SS Rear Derailleur
Thanks to highly innovative, digital technology, this rear derailleur guarantees remarkably fast and precise shifting action - perfect for top level riding and racing.
- Programmed motion allows for quicker and smoother shifting with less chain drop
- Servo motor keeps gear changes identical and precise every time, as the computer control unit analyzes each shift
- Built-in saver (fuse) function moves the derailleur inward under impact, reducing the potential for damage in the event of a crash
- Derailleur recalibrates and realigns itself with the cassette following an impact
- Carbon pulley cage and P-body with titanium B axle lighten the load while maintaining strength, rigidity and performance
- Expanded chain wrap capacity accommodates a maximum 27 tooth cog for better compatibility with compact cranks
- Short cage design
- Must be used in conjunction with the Shimano Dura-Ace Di2 7970 Rear Derailleur Wire Kit, Shimano Dura-Ace Di2 7970 SM-BTR1 Battery Pack, Shimano Dura-Ace Di2 7970 SM-BCR1 Battery Charger and Shimano Dura-Ace Di2 7970 SM-BCC-12 Power Cable
