SRAM Type 2 Rear Derailleur

SRAM's new TYPE 2 rear derailleur will come to the X0 and X9 families and offer a built in roller clutch mechanism that virtually eliminates chain slap and noise. To ease rear wheel removal and entry, the Cage Lock holds the derailleur open to make the chain slack, countering the stiff return tension of the clutch. For the full lowdown, check Bikerumor.com
