Rear derailleur. 11 speed. Long cage. Your needs aren't less demanding, they're different. The SRAM Rival 1 rear derailleur is engineered for smooth, reliable shifting action, delivering 100% of what you demand. By eliminating unwanted chain movement, X-HORIZON™ shifts faster, reducing shift effort and chain slap.

• A dedicated SRAM 1x™ rear derailleur
• Exact Actuation™ for fast and accurate shifts using SRAM's 1:1® actuation ratio (shifter cable travel : derailleur movement)
• X-Sync™ pulley features a 12-tooth design that helps control the chain's lateral movement
• Roller Bearing Clutch™ controls chain tension for consistent shifting
• X-Horizon™ straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force
