The SRAM Force 1 rear derailleur is designed for 1x road and gravel drivetrains — bringing the simplicity of a single chainring to Force-level road shifting. Hydraulic Bottom Pull technology and the Force clutch keep chain tension consistent across varied terrain, making the Force 1 a serious option for gravel and mixed-surface road riding.

Highlights

  • Force 1 11-speed road/gravel 1x rear derailleur
  • Clutch mechanism for improved chain retention on rough surfaces
  • Compatible with Force 1 DoubleTap shifters and X-SYNC chainrings
  • Wide-range cassette capacity for 1x road and gravel gearing
  • Eliminates the front derailleur for a cleaner cockpit

Force-level 1x

Force 1 was one of the first road-specific 1x drivetrains — designed for gravel and adventure riding where a single chainring simplifies cockpit management and reduces maintenance. The clutch engages to prevent chain bounce on rough surfaces, a feature borrowed from SRAM's MTB drivetrains and applied to the road context.

Fit and compatibility

11-speed road/gravel 1x rear derailleur. Compatible with SRAM Force 1 DoubleTap shifters. Confirm maximum cog size and cage length for your cassette before ordering.

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
