SRAM GX 2x10-Speed Rear Derailleur Item # 893973
Description
Leveraging the legendary history of SRAM shifting, the GX 2x10 rear derailleur provides incredible shifting speed and precision. EXACT ACTUATION technology eliminates slop and shifting variation. ROLLER BEARING CLUTCH technology delivers maximum drivetrain stability-even through the most punishing terrain. And with CAGE LOCK technology, wheel removal and installation are easier than ever.
Features:
- EXACT ACTUATION for precise and dependable 10-speed performance
- TYPE 2.1 technologies: ROLLER BEARING CLUTCH and CAGE LOCK (also available without TYPE 2.1 configurations)
- Cage lengths: Short, Medium and Long
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.

Replaced X7
A Giant Reign with a 3x10. Got a bent hanger and a broken derailler. Replaced it with the GX as the X7 or X9 no longer seem available. Fitted and adjusted fine, works as it should. Perfectly happy with the part and the phone sales guy was both knowledgeable and very helpful checking compatibility for the bike. Great service.
