The SRAM 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.
A dedicated 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
X-HORIZON™ “straight parallelogram” design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force
