SRAM X9 10 Speed Rear Derailleur


The SRAM X9 10 Speed Rear Derailleur uses SRAM’s Exact Actuation technology for precise and dependable 10-speed performance, while a carbon and alloy cage makes it light and tough at just 204 grams for a medium sized cage. For those riders looking to give their ride that little bit of extra colour matched style, the SRAM X9 rear derailleur comes in 3 different colour ways.


The Exact Actuation system uses a 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed shifting. This Exact Actuation helps to simplify and stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up, and it stays that way.





Outer and inner are forged from 6061 D-stamp aluminium on long and medium cage models, small cage models use composite cages

Jockey Wheels:

Sealed cartridge bearing upper pulley


10-speed only maximum 36 tooth cassette compatibility


Aluminium alloy links and forged B-knuckle, high strength Grilon P-knuckle with a 6061 D-stamp alloy outer and inner cage on the long and medium models with the small size benefitting from a composite cage design


204 grams for medium cage
