The SRAM Force 1 rear derailleur adopts all the technologies of SRAM 1x MTB to provide the fastest, quietest 1×11 shifting available. SRAM’s unique clutch system eliminates chain slack, providing for smoother, quieter, and more secure chain travel.

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
A dedicated SRAM 1x rear derailleur
