SRAM X9 Rear Derailleur
Shaving grams and shaving seconds, this mountain bike rear derailleur is lighter and slimmer than a model for a new diet program. But don't let the the super-light, low-profile chassis fool ya -- this SRAM derailleur is tougher than it looks. Loads of planning and design went into making this mountain bike derailleur, and the result is exactly what you'd expect from SRAM: smooth, exact shifting; precision feel and long-term reliability.
