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

• A dedicated 1x rear derailleur
• ROLLER BEARING CLUTCH™'s one-way 3.0 roller clutch controls chain tension for consistent shifting
• 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
• 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
• For use only with single chainring drivetrains
