The SRAM GX 2x10 rear derailleur brings proven speed and precision to your drivetrain. With Exact Actuation technology for consistent shifting, Roller Bearing Clutch for stability on rough terrain, and Cage Lock for quick wheel changes, it delivers reliable performance ride after ride.

Technology

• CAGE LOCK
  With CAGE LOCK technology in the rear derailleur, wheel removal and installation - as well as chain installation - becomes faster and simpler. Just push the cage forward to create slack and lock it into place.
  
• DIRECT ROUTE
  Here's the dirt on middlemen: they suck. That's why DIRECT ROUTE technology doesn't have one. Instead, the cable routes directly to the actuation mechanism. Result? Less friction. Less effort. More oomph. Plus it's impervious to cable housing damage. Nice.
  
• EXACT ACTUATION
  When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement). EA 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.
  
• ROLLER BEARING CLUTCH
  ROLLER BEARING CLUTCH technology eliminates derailleur bounce and chain slap without sacrificing precision.a
