Sram Force 1 Type 2.1 11 Speed Rear Derailleur
Sram's top of the line Force 1 rear derailleur functions at its peak in cyclocross or gravel surrounding. With X Actuation and X Horizon, the Force 1 rear derailleur out performs other shifting systems. The X-Horizon derailleur knuckle only moves side-to-side — not up-and-down. This limits the movement to the horizontal axis, making ghost shifting nonexistent. Also, the derailleur upper pulley is offset, which provides a constant chain gap through all of the gear ratios. With the combined efforts of the X-sync chainring, pulley wheels, and a Roller Bearing Clutch, a chain guide isn't needed with your drivetrain. Your chain is tensioned with the derailleur and locked in place with the pulleys and chainring. Combining the Roller Bearing Clutch and parallelogram design means that you'll never get chain slap. The derailleur is also made to withstand repeated hits while you're navigating through a rough terrain in order to eliminate the chance of throwing the chain. The Force 1 derailleur also comes equipped with the lock out button, allowing you to make wheels swaps or any fix ups a breeze.
Sram's Force 1 rear derailleur can only work with 1x11 set up with, with sram's 11 speed road shifter and cassette.
