SRAM X4 Rear Derailleur - 7,8,9 Speed
What does the SRAM X4 Rear Derailleur offer for budget builds?
The X4 is SRAM's entry-level 7/8/9-speed rear derailleur, and it punches well above its price point for repairs, commuter builds, and budget trail setups. The 1:1 Actuation ratio is SRAM's proven shifter-to-derailleur standard, delivering precise light-action indexing that stays in tune through everyday riding. The cage geometry handles cassettes in the standard range for 7, 8, and 9-speed systems without needing any adjustment to the cage length spec.
Built for reliability over flash, the X4 is a no-drama workhorse that installs cleanly on any standard derailleur hanger and works with SRAM trigger or grip shifters using the same actuation ratio. If you are repairing an older build, setting up a commuter, or spec-ing a budget trail bike without cutting corners on shifting consistency, this is the derailleur that makes it work at a price that actually makes sense.
