SRAM X9 Type-2 10 Speed Rear Derailleur
Type 2 adds the Roller Bearing Clutch to a normal X.9 derailleur to deliver maximum drivetrain stability, even through rough terrain. This clutch eliminates bounce and chain slap without sacrificing precision. Clutch is self-lubricating, maintenance free, uses needle bearings, and comes factory calibrated from SRAM.
