SRAM Rival 1 11-Speed Type 3 Rear Derailleur - Medium

The SRAM Rival 1 Type 3 rear derailleur is engineered for smooth, reliable shifting action - from the larger upper pulley offset to the 12-tooth X-SYNC pulley wheels. By eliminating unwanted chain movement, X-HORIZON shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with CAGE LOCK technology, wheel removal and installation are easier than ever.
