Force1 Rear Derailleur 11-Speed

SRAM's Force 1 rear derailleur adopts all the technologies of SRAM 1x™ MTB to provide the fastest, quietest 1x11 shifting available. SRAM's unique clutch system eliminates chain slack, providing for smoother, quieter, and more secure chain travel.

Key Features:

• 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™'s one-way roller 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
  
• Cage Lock™ technology makes for fast wheel changes or chain installation
