SRAM Red Black Rear Derailleur 2011

Based on the design of the SRAM Force rear derailleur, the Red Black offering delivers even greater advantages thanks to a diet of structural carbon and titanium. Hybrid ceramic bearing jockey wheels and the titanium parallelogram spring further supercharge the overall component's speed, accuracy, and durability.

Nominal weight is an astonishing 153g mechanism. Applies SRAM's 1:1 actuation ratio (shifter cable travel to derailleur movement) for 10-speed shifting, Exact Actuation helps deliver the easiest index shifting system to set up - and it stays that way.
