For some of the smoothest and fastest shifting on the market, look to the SRAM Force1 Rear Derailleur Medium Cage 11-Speed. Utilising SRAM's Exact Actuation technology, this derailleur provides a 1:1 actuation ratio for seamless shifting with either 10 or 11 speed setups.
SRAM Force1 Rear Derailleur Medium Cage 11-Speed
SRAM Force1 Rear Derailleur Medium Cage 11-Speed
Designed to maintain a steady pulley-cassette gap across all gear ranges, the SRAM Force1 Rear Derailleur Medium Cage 11-Speed uses SRAM's one-way roller bearing clutch to control chain tension for consistent shifting.
With Roller Bearing Clutch Technology, derailleur bounce and chain slap are eliminated without sacrificing precision.
The mech also uses SRAM's Exact Actuation for fast and accurate shifts using SRAM's 1:1 actuation ratio (shifter cable travel; derailleur movement) and is 10 and 11 speed compatible.
The derailleur is finished with cage lock technology which makes wheel removal and installation, as well as chain installation faster and simpler. Simply push the cage forward to create slack and lock it in to place.
- 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.
