Shimano Dura-Ace 7900 Rear Derailleur

The Shimano Dura-Ace RD-7900 rear derailleur is the first rear derailleur made by Shimano to feature carbon fiber. The use of carbon fiber helps to shed weight while keeping the derailleur strong and by crafting the rest of the Dura-Ace RD-7900 out of forged aluminum, Shimano ensures a long and productive life for your derailleur. One of the top features of the Dura-Ace RD-7900 is a new larger chain wrap capacity which allows this derailleur to work with a wider range of gear ratios. To help give the Dura-Ace RD-7900 the performance you've come to expect from the Dura-Ace line, Shimano has given it a wider link design to make it stiffer which makes your shifting smoother. The Shimano Dura-Ace RD-7900 rear derailleur is a 10 speed rear derailleur and comes as a short cage. Includes hardware.
