SRAM Force 1 Rear Derailleur

SRAM adopted the brilliant 1x technology from its MTB brethren for the Force 1. This rear derailleur features SRAM's Exact Actuation technology for precision shifts every time, across all 11 gears. With a roller bearing clutch to control chain tension and an X-Sync chain pulley to control lateral movement, you get smooth, quiet, and secure shifting and operation on even the most intense cyclocross courses.

- A dedicated 1x rear derailleur
- Exact Actuation for fast and accurate shifts using SRAM’s 1:1 actuation ratio (shifter cable travel: derailleur movement). 10 and 11-speed compatible
- 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
- ROLLER BEARING CLUTCH’s one-way roller clutch controls chain tension for consistent shifting
- CAGE LOCK technology makes for fast wheel changes or chain installation
- Weight: 261 grams (medium cage) 271 grams (long cage)
- Largest Cog (teeth): 36 (medium cage) 42 (long cage)
