The SRAM X4 Rear Derailleur is engineered to provide precise and dependable shifting for 7- or 8-speed mountain bike drivetrains. Built with a robust blend of aluminum and steel, this derailleur is designed to withstand the rigors of rough trails while maintaining its performance over the long term. It is an ideal choice for riders looking for a durable, entry-level component that delivers a consistent feel across various terrains.

Utilizing SRAM's 1:1 Actuation Ratio, every millimeter of cable pulled translates to an equal movement of the derailleur, ensuring a setup that is easy to tune and highly resistant to contamination or cable stretch. The direct cable routing further enhances shifting speed by reducing friction and eliminating unnecessary housing loops. This combination provides a quick, reliable mechanical response for a confident riding experience.
